Thread Dump

In a dynamic web module, opening any Servlet or ServletContextListener causes the UI to freeze (as in Windows' Not Responding) for approximately 10 seconds. Once the UI is responsive again, scrolling through the does not cause any further problems, but any modification, no matter how small, again completely freezes the UI for several seconds at a time. Likewise, the UI hangs up for again around 10 seconds when closing the editor tab/file.

It is noteworthy that the issue does not occur when the project is collapsed in the Project Explorer and the Servlet or Listener is opened directly, e.g. via Ctrl-T.

I am attaching two separate thread dumps taken at a time when the UI was non-responsive after opening an offending class.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
