Find Usages mixed reads and writes of a Java field, including Lombok getter and setter calls, because jdtls has no read/write classification in its references. The usages popup and Find window now have Read and Write toggles. Read-write accesses stay visible in either mode and unclassified results are kept.
Classification comes from a jdtls extension in `plugins/java-usages`, embedded as a jar and installed beside the other bundles. The checked-in jar was rebuilt from source with ECJ and matches byte for byte. Any extension failure falls back to standard references, so a jdtls upgrade can lose the filter but not Find Usages; rebuilding the jar on an upgrade is manual and described in the plugin README. Older installed jars are removed. Other languages keep their plain result count.
