Description

When I just open NetBeans (nothing else), it keeps displaying exceptions (red speech bubble in the status bar) all the time. It also doesn't finish scanning my projects, rather gets stuck at 98%.

 

At this time NetBeans (permanently) keeps consuming 23% CPU on a computer with 8 cores.

The exception it keeps throwing is this:

GitInterceptor.refreshTask: Scanning in progress, trying again in 10.000ms 

I'm suspecting that being stuck at 98% may be related to these exceptions, but I'm not sure.

My previous version is NetBeans 10.0, where this problem doesn't occur with the same project being open at startup. So far I can't work with 12.2. As it seems, the bug doesn't happen in version 12.0.

Please let me know which other information you need to track the problem.
