harshaindunil opened a new pull request, #9366:
URL: https://github.com/apache/netbeans/pull/9366
## Summary
Implements a Java-editor-only reference count hint feature for methods and
named types.
The editor shows an above-line reference count, opens a lightweight popup on
click, and still allows opening the existing full Find Usages UI.
This is the initial Swing Java editor integration only. It does not attempt
LSP or non-Java editor support.
Fixes #8230.
## Main changes
- add Java reference count hint computation and publishing in `java.editor`
- add above-line block hint rendering support in `editor.lib2`
- add a completion-style usages popup from the hint click action
- reuse Java Where Used / Find Usages semantics for counts and navigation
- add Java inline-hints options for enabling reference counts
- add tests around direct reference counting and `TreePathHandle` resolution
fallback
## Performance / behavior notes
- counts are computed in background tasks
- counts are limited to visible declarations and refreshed as the viewport
changes
- cached values are reused instead of clearing the full file on every index
event
- existing hints remain visible while recomputation is deferred during
scanning
- split editors for the same document are handled correctly
## Validation
Manual validation in the built IDE:
- Java editor rendering of above-line hints
- click opens the reference popup
- popup can open full Find Usages
- dark theme rendering
- split editor behavior
- scrolling / viewport refresh behavior
- indexing refresh behavior
I also rebuilt the affected modules and the IDE image during development.
## Follow-up scope intentionally excluded
- LSP / generic editor integration
- non-Java languages
- an alternative lazy, non-inline usage action mode
