Editor goes nuts adding a new line or adding to a comment

Apache NetBeans version

Apache NetBeans 24

What happened

I noticed this with NB 23 as well, btw. Using java, when trying to insert a new line to add something like
Integer i = 2;,

the editor instead does something like

        I nteger a = 1;
        ;
        Agency agency = entityManager.find(Agency.class, agencyId);

You can see it starts with the capitalized 'I", followed by a space and then the following line gets appended so you are typing in the blind. This used to work with version 23 for a while but then this started happening. When I then first upgraded to 24, that 'bug' disappeared, but now re-appeared a few weeks ago again.
What I have tried:
Re-install NB with no JDK included. Tried running against java 17, 19, 21 and 23.
Re-Install NB with prepackaged JDK.
Deleted NB cache and restarted.
None of these worked. Not sure if I should completely wipe out my .netbeans folder and start from scratch.

I dropped a couple of screen recordings, since it is kind of hard to write-up the behavior of the IDE.

How to reproduce

Like I said, this suddenly started happening for me. Since I am not seeing many reports, expect for very old versions of NB, it is probably not easily reproducible, but maybe you have some suggestions.

Did this work correctly in an earlier version?

Apache NetBeans 23

Not sure if I should completely wipe out my .netbeans folder and start from scratch.

one easy way to quickly check something is to start netbeans with a fresh temporary config (this will put the cache into the same folder). Also don't import the settings on first start to exclude it as a possible cause.

netbeans --userdir /tmp/tmpusr1

your log doesn't look good though:

this is the unused imports hint failing. Wondering if turning it off helps (under Hint settings Imports -> Unused Imports).

WARNING [org.netbeans.modules.parsing.impl.indexing.LogContext]: Excessive indexing rate detected: 6 in 2mins, treshold is 5. Dumping suspicious contexts

this is also unusual. Are we dealing with huge projects or very big project groups? I could only reproduce things like this in load tests where I opened hundreds of projects on startup.

Thanks Michael, I did notice both those exceptions and the indexing. I have about 5 multi-module maven projects and I can try to close a few if you think that helps since I usually jump only between 2 of them. As a first test, turning off the hint option seems to have helped. If it helps, the classes don't have unused imports. At least I am now unable to reproduce what you saw in the recordings I uploaded. It puzzles me though, why this wasn't a problem before and then out of nowhere manifests itself. I will continue working with just this change and let you know in a week or so, if the problem persists. Thanks for the quick response, Bas
