Lukas Theussl commented on NETBEANS-5154:
-----------------------------------------
Same problem here, quite a show-stopper. It doesn't happen with 12.1, so it
seems to be a recent regression.
> NetBeans 12.2 keeps throwing exceptions all the time
> ----------------------------------------------------

> Key: NETBEANS-5154
> URL: https://issues.apache.org/jira/browse/NETBEANS-5154
> Project: NetBeans
> Issue Type: Bug
> Affects Versions: 12.2
> Reporter: TLX
> Priority: Major
> Attachments: image-2020-12-15-20-50-10-740.png
>
>
> 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%.
>
> !image-2020-12-15-20-50-10-740.png!
> At this time NetBeans (permanently) keeps consuming 23% CPU on a computer
> with 8 cores.
> The exception it keeps throwing is this:
> {code:java}

> My previous version is NetBeans 10.0, where this problem doesn't occur with

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