CommentListener causes Memory Leak #300

Closed mpetris closed 2 years ago

mpetris commented 2 years ago

Describe the bug In the TaggerView of the Annotate Module on loading a Document a CommentListener is registered in Hazelcast for the Comments-Topic on that Document. That CommentListener keeps registered even after closing the TaggerView. Since the CommentListener maintains a reference on the Project itself, the whole Project is kept from being GCed after closing the Project.

To Reproduce Steps to reproduce the behavior:

  1. Check instance count of GraphWorkTreeProject
  2. Open a Project
  3. Open a Document
  4. Close Project
  5. Check instance count of GraphWorkTreeProject

Expected behavior Instance count should be the same as before opening the Project.

Some CommentListeners doesn't get removed, probably on session destroy.
