NPE on JsonArray.size() codeAction failure in VSCode after getData() is null

[evie-lau]

[Error - 2:07:32 PM] Request textDocument/codeAction failed.
  Message: Request jakarta/java/codeaction failed with message: java.lang.NullPointerException: Cannot invoke "com.google.gson.JsonArray.size()" because "diagnosticData" is null
  Code: -32603 

To reproduce:

• In ScopeDeclaration.java, hover over the diagnostic for the method

Files that seem to call this method and may have this issue:

• lsp4jakarta/jakarta.jdt/org.eclipse.lsp4jakarta.jdt.core/src/main/java/org/eclipse/lsp4jakarta/jdt/core/cdi/ScopeDeclarationQuickFix.java

  Line 47 in 5e9163e

  List<String> annotations = IntStream.range(0, diagnosticData.size())

• lsp4jakarta/jakarta.jdt/org.eclipse.lsp4jakarta.jdt.core/src/main/java/org/eclipse/lsp4jakarta/jdt/codeAction/proposal/RemoveMultipleAnnotations.java

  Line 55 in 5e9163e

  List<String> annotations = IntStream.range(0, diagnosticData.size())

This is likely caused by the getData() is null problem.

    JsonArray diagnosticData = (JsonArray) diagnostic.getData();

    List<String> annotations = IntStream.range(0, diagnosticData.size())
