Jakarta quick-fix fails due to getData() is null

[turkeylurkey]

Certain quick fixes related to Jakarta do not appear with the diagnostic in the editor because of an exception.

You can see the exception in the Output tab when you select "Language Support for Java."

[Error - 12:57:13 PM] Request textDocument/codeAction failed.
  Message: Request jakarta/java/codeaction failed with message: java.lang.NullPointerException: Cannot invoke "Object.toString()" because the return value of "org.eclipse.lsp4j.Diagnostic.getData()" is null
  Code: -32603

An example is the quick fix reading "The @AssertTrue annotation can only be used on boolean and Boolean type fields."

More details are available in the lsp4jakarta repository.

Raised a PR with fix in lsp4Jakarta repo - eclipse/lsp4jakarta#536

@aparnamichael now that eclipse/lsp4jakarta#536 has been merged, please verify this fix is resolved using the latest LSP4Jakarta 0.2.2-SNAPSHOT build. You will need to manually delete the language server jars and then re-run npm run build. Make sure LSP4Jakarta 0.2.2-SNAPSHOT is specified in all the correct locations. You can refer to #361.

Tested with LSP4Jakarta 0.2.2-SNAPSHOT, the null pointer exception is resolved, and the quick fixes are functioning as expected.
