Java debugging resolved the launch and built the workspace before a debug session existed, so during a jdtls build of up to 20 minutes there was no way to stop. A starting notification with Stop now appears before preparation begins, using the same pattern as waiting for a remote JVM. Stop cancels the resolve request, and a late response neither starts a session nor reports an error. Real resolve failures report as before.
java/buildWorkspace builds the whole imported jdtls workspace, and its 5-minute cap failed launches in large multi-module projects. The budget is now 20 minutes, and the timeout error names it so a real stall can be told apart.
Waiting that long needs a way out, so java_resolve_launch now takes a RequestId and is cancellable locally and over remote. The token reaches the jdtls ready and import waits, the requests (sending $/cancelRequest), and the external build. Stopping a run session during this phase cancels silently and does not launch. Starting a debug session passes a request id but has no stop path yet.

Follow-up to #385. A single output event can carry thousands of lines, which became one console entry and escaped the line cap; output is now split at real line breaks (partial lines still merge across events) so the 50,000-line bound applies to physical lines. The host also coalesces debug output per session for up to 50 ms / 64 KB before it reaches desktop or remote IPC, flushing before any other session event so stops and exits never overtake earlier output.
Verified on macOS with a Java program printing ~480 lines/s for over a minute: the console stays responsive, follows the tail, and pause/step work.
Fixes#377
Each DAP output event copied the whole console array and re-rendered every buffered line, so a debuggee writing continuously to stdout froze the window after tens of thousands of lines. Output is now queued and applied once per animation frame (merged per session and category), the buffer is capped (50,000 entries, plus the console buffer-size setting), and the Debug console renders only the visible rows.

Kotlin line breakpoints never verified through java-debug because jdtls cannot resolve classes for .kt files. Kotlin Application configurations and JDWP attach for modules with Kotlin sources now use the official Kotlin Debug Adapter (installable from the debugger prompt, running on the language-server JDK); pure Java keeps java-debug.
The adapter resolves classes from source paths, so sources whose directories don't match their package are mirrored package-aligned outside the project (symlinks, copies where links fail) and paths are mapped back for breakpoints and stack frames; files that can't be mirrored are skipped rather than failing the session. Kotlin applications start with JDWP suspend=y and a session-owned JDWP relay holds the adapter's early resume until attach completes, so breakpoints are installed before the program runs.
Limitations (docs/kotlin-debugging.md): @file:JvmName facades are not resolved; package/source-root changes need a new session. Not verified on a real Windows machine.
Fixes#374
Adds Tomcat Server › Local run configurations for WAR applications: installation validation and version detection, Maven/Gradle WAR artifact discovery and build before launch, WAR file or exploded-directory deployment, context path and HTTP port, project JDK or a chosen JRE, VM options, environment variables and opening the browser.
Each configuration runs with its own CATALINA_BASE in the project cache (HTTP, shutdown and local JMX ports configured there); Stop requests a clean shutdown before the usual process timeout. Debug attaches the Java debugger over JDWP. Update Application (Cmd+F10) updates resources, classes and resources with HotSwap, redeploys or restarts the server. Configurations are grouped under Tomcat Server in the configuration tree and Services.
Not verified on a real Windows machine; command construction is unit tested.
Fixes#205
java-debug treated forward-slash Windows drive paths as URIs, so breakpoints never verified; source paths are now sent with native separators and mapped back for stack frames and breakpoint events. Debug sessions also flush every file's pending breakpoint updates before starting, so configurationDone never runs with an empty breakpoint snapshot (all adapters, launch and attach).
Not verified on a real Windows machine; the path conversion is covered by unit tests.
Fixes#380
Refs #374
With several sessions running, the toolbar's Rerun and Stop could act on a different configuration than the selected one: when the selected configuration had no matching run session, the widget fell back to the most recently started session of another configuration; and debug sessions did not record the configuration they were started from, so a configuration being debugged never matched and a running npm session took over the buttons.
The widget, Run (Shift+F10) and Stop (Cmd+F2) now target the selected configuration's session, whether it was started with Run or Debug (the most recent when both exist); Rerun of a debug session reruns it in debug. When the selected configuration is not running, the widget offers Run / Debug for it, and Stop remains available for the other running sessions (with a chooser when several are running). Debug sessions keep their originating run configuration. In a focused Run or Debug tool window, Stop still stops the selected tab's process.
Fixes#318
Only the JVM the IDE launched directly was told the console's output encoding, so forked JVMs (spring-boot:run, Surefire, bootRun, Gradle workers), debugger-launched JVMs and Build-window builds wrote GBK on Windows while the console decoded UTF-8. Every JVM the IDE starts on Windows now gets the console encoding: java gets -Dfile.encoding alongside the std* properties, build tools and their forks get JAVA_TOOL_OPTIONS (std* only) with the IDE's own 'Picked up JAVA_TOOL_OPTIONS' line filtered, shell command lines are recognised by their first word, and java-debug launches get the matching vmArgs. The Debug console now shares the Run console's ANSI parser. Encoding helpers moved to ide-core::output_encoding.
Not verified on a Windows machine.

Adds Application and Spring Boot run configuration types with main class, VM options, program arguments, classpath and active profiles. Maven passes them through spring-boot.run.jvmArguments / profiles / argLine; Gradle through an init script.
Fixes#187
Claude-Session: https://claude.ai/code/session_01Dq6jQQn8ZhRfkkyj3PRutA
java-debug runs inside jdtls and is reached through its debugServer port, but configurations that aren't Application / Spring Boot and select java-debug (a Shell Script running `catalina.bat run`, say) fell through to the generic launch template, and the adapter launcher tried to start com.microsoft.java.debug.plugin.jar as a process: on Windows that failed with os error 193, elsewhere with a misleading "debug adapter not found".
- Shell script / program configurations with java-debug start with a suspended JDWP agent injected through JAVA_TOOL_OPTIONS and attach once the JVM prints its port, so `catalina.bat run` / `catalina.sh run` can be debugged.
- Maven goals that run the app in Maven's JVM (tomcat7:run, jetty:run(-war), exec:java, or any Maven config with java-debug) are debugged through MAVEN_OPTS.
- Gradle tasks that start no JVM say why they can't be debugged; `debug.startConfig` with a single debuggable config goes through the run debug flow.
- .jar adapters are never spawned as processes, and Windows adapter lookup only accepts PATHEXT files (so npm-installed adapters pick the .cmd shim instead of the POSIX one); the PATHEXT expansion moves to ide_core::process::executable_names, shared with ide-run.
Not run on Windows; the Windows resolution is covered by tests with an injected platform.

Settings › Debugger › Data Views gains Show value tooltip on code selection
(on by default). While the debugger is paused, selecting an expression on one
line shows its value once the selection settles, with objects expandable like
the hover tooltip.
Settings › Debugger › Data Views gains Sort values alphabetically (off by
default). When on, variables and their children are listed by name, comparing
numbers numerically; array and list elements keep their index order.
Run oxfmt once over the whole repository (formatting only, no logic changes) and add `pnpm format:check` to the frontend CI job so unformatted code no longer builds up. `.oxfmtrc.json` now skips the generated theme docs, test fixtures and code blocks inside Markdown.

Adds GDScript, Godot resource and shader file types with tree-sitter highlighting, the GDScript language server over TCP (a headless Godot editor started on demand), "Godot Project" / current-scene run configurations, and debugging through Godot's debug adapter.
Breakpoints set through symlinked paths (/tmp, /var on macOS) were reported verified but never hit; the adapter now sends resolved paths and maps stack frames back to the paths the IDE opened. The duplicate exit event Godot sends after disconnect is ignored.

Root cause: run configurations could only launch a process; there was no "attach to a debugger that is already listening" type, and debugServer only connected to 127.0.0.1.
Fix (IDEA / GoLand / PyCharm): debug-only Remote JVM Debug (attach / listen, live JDWP agent args per JDK version), Go Remote (dlv --headless, substitutePath), Python Remote Debug (debugpy --listen, pathMappings) and Attach to Node.js (inspector, localRoot/remoteRoot); debugServer accepts host:port and [v6]:port; JVM listen mode via a cancellable relay so java-debug can attach.
Verified: ide-dap tests (host:port, relay handshake, cancel), run/debugger vitest, in-app on macOS: Python Remote Debug attached to a debugpy server, paused at app.py:3 with variables. Remote JVM/Go/Node not exercised in-app.
Claude-Session: https://claude.ai/code/session_01VUYsdXA2nkF5v6zsC93dpn
Root cause: every java launch inlined the whole classpath into one -cp argument with no "Shorten command line", so long classpaths exceeded CreateProcessW's 32767-char limit (os error 206) before the JVM started.
Fix (IDEA's auto "Shorten command line"): ide-run rewrites a too-long java command line at spawn time — @argfile on JDK 9+ with ASCII paths, otherwise a MANIFEST pathing jar (percent-encoded file: URLs, 72-byte lines); temp files are removed when the process exits. Debug passes the same choice to java-debug's shortenCommandLine.
Siblings covered: Application/Spring Boot, test classpath, Kotlin main, explicit java -cp configs, profiler, PTY launches, Debug.
Verified: unit tests, pathing jar loaded by real JDK 8/11/25, ProcessManager integration test with 3000 entries on JDK 8/17/25. Not verified on Windows.

* fix(vcs): Label restored local changes as yours after Smart Checkout; name the branch checked out
Conflicts from restoring stashed changes show the user's uncommitted
changes on the left like other operations, and the checkout notification
names the new branch instead of the previous one.
* fix: Close the merge editor on Apply; confirm before terminating a running Run tab
Like IDEA, applying a merge result closes its tab, and closing a Run tab
whose process still runs asks before terminating it (with a Settings
toggle and "Do not ask again").
* fix(terminal): Don't start a new session in the background after closing the last tab
The hidden Terminal window stays mounted, so it reopened a session as soon
as the last tab closed. It now opens the Local tab only once the window is
shown again, as IDEA does.
* fix(vcs): Start the merge result from a three-way merge; close the editor on Apply
The result pane now begins with non-conflicting changes merged and each
conflict showing the base text, resolved from the side panes, instead of
raw conflict markers. Apply now reports success, so the tab closes.
fix(search): Match File Structure filter on word starts
* fix: Limit Smart Step Into to the paused line; drop usages hints on callbacks; show full intention titles
Adapters that list every remaining call in the function (debugpy) made Smart
Step Into fall back to a chooser that offered calls from later lines. Targets
are now narrowed to the calls on the paused line, so they are picked in place.
Anonymous functions and callbacks no longer get a 'no usages' hint, and
intention titles are no longer cut short when there is room for them.
* fix: Undo / Redo from the Edit menu and Find Action use the editor's history
They ran the webview's native undo, which misses programmatic edits such as
templates, completion and refactorings, so nothing happened in the editor.
* feat(nav): Complete file paths and flag unresolved web file references
Path completion in href/src/url()/@import, Markdown links and path-like strings, folders first. HTML and CSS paths that name no file get a 'Cannot resolve file' warning. File references resolve in the backend like IDEA's: relative to the file, /-rooted against the project and resource roots.

* fix(java): Run jdtls with a Lombok agent and show build errors at launch
jdtls compiles with ECJ, which only generates Lombok members when the
server JVM runs -javaagent:lombok.jar. Nothing put it there, so @Data /
@Setter classes lost their accessors and Run launched stale classes
with "Unresolved compilation problem" stubs and no explanation.
- Projects whose build files mention Lombok get the newest jar: the
IDE-managed one (new "Lombok (jdtls agent)" tool, latest release from
Maven Central), else ~/.m2 (incl. settings.xml localRepository) or the
Gradle cache. Each agent gets its own jdtls workspace so everything is
rebuilt with it.
- Settings › Languages & Frameworks › Java › JVM options
(java.jdt.ls.vmargs); a Lombok agent there wins.
- Run (and Debug, as a notification) list the first compile errors when
the build has errors, plus a hint when Lombok is missing or older than
1.18.34.
Fixes#3
* fix(java): Base the Lombok hint on the agent jdtls actually runs
A Lombok agent in Settings › Java › JVM options wins over the managed
and cached jars, but the launch hint still looked only at those: with
no cached jar it said Lombok was missing, and with an old cached one it
blamed that version although jdtls ran the user's. The hint and the
startup warning now use the user's agent (version from its file name).
