Java Language Server fails with classes that extends sealed class.

[UnnamedXAer]

I'm not able to use rename, quick fix, go to definition when editing class that extends sealed class.

Environment

• Operating System: Windows 11
• JDK version: 22
• Visual Studio Code version: Version: 1.88.1 (user setup)
• Java extension version: v1.30.0

Steps To Reproduce

1. Try to rename argument of method in class that extends sealed class.

[Please attach a sample project reproducing the error]
https://github.com/UnnamedXAer/java_language_server_issue_sealed

// .../Storage.java
public abstract sealed class Storage implements AutoCloseable
    permits SqlStorage {
  public abstract Object get(int id) throws Exception;
}

// .../SqlStorage.java
public final class SqlStorage extends Storage {

  @Override
  public void close() throws Exception {
    // TODO Auto-generated method stub
    throw new UnsupportedOperationException("Unimplemented method 'close'");
  }

  @Override
  public Object get(int id) throws Exception {
    // TODO Auto-generated method stub
    throw new UnsupportedOperationException("Unimplemented method 'get'");
  }

  private String add(String a) {
    return String.format("%s%s", a, a);
  }
}

Current Result

Popup saying 'Internal error';

Expected Result

Rename box;

Additional Informations

In more advanced scenarios (classes) most of the LSP related features do not work.

[rgrunber]

Looks similar to eclipse-jdt/eclipse.jdt.core#1641. Maybe this is another way of triggering the problem that hadn't been predicted upstream.

Was able to easily reproduce by calling code completion in a source file that extends a sealed class.
