When debugging in Eclipse, it seems that randomly (but quite frequently) the focus on the paused thread gets lost and buttons to perform debugging (Step Over, Step Into, Resume) get disabled. You are no longer able to continue debugging step by step, you need to set another breakpoint and resume the debugger to that breakpoint.

Another workaround is to move the Debug view from one location to another in order to force a repaint. In this situation, the list of threads is refreshed and you are able to continue the debugging.

This issue has been reproducing for quite some versions now.

The same problem was already reported until now and was closed with various reasons:
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=372941
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=187000

This bug is very serious and affects the productivity of the developers.

On version 12-2019 the problem was not manifesting, while on version 09-2020 we managed to reproduce it.
Although we don't think it might be of any importance, we are using the following plugins:
* IvyDE
* Payara Tools
* SonarLint 6.1
* Spring Tool Suite 4.12.0

This looks just like Bug 476276 (and perhaps 10 others).

Any update on this? Still happens, especially if the application creates/destroys other threads.
