Anything else

After the first occurrence, I'm not able do debug anymore because of this error always occurring.

Code of Conduct

Yes

[c-rosati]

I've just installed NetBeans 15 and the same problem exists, so I lost the possibility to debug code.

[c-rosati]

I've found the problem. I've disabled all User Installed Plugins and debugging was working fine without exceptions. Re-enabling the plugins if found the cause:

BinEd - Binary/Hexadecimal Editor, ver. 0.2.3

Disabling (and then uninstalling) it fixed the issue.

[neilcsmith-net]

As noted in #3797 BinEd does some creative things to register its actions. Some things even persist after uninstall. Please report this issue to the author. Closing this. Thanks!

Hey @c-rosati please check with latest NetBeans 15 (I think NetBeans 16 is around the corner) and with newest Bined-netbeans-plugin 0.2.4 (https://bined.exbin.org/netbeans-plugin/)
