Linux 5.6.8-200.fc31.x86_64 amd64
Java 14.0.1

When I edit text in the entry editor, I often get this exception, without further action. I suspected it might be related to autocompletion, but I read @Siedlerchr as this not being the case at #6351. As you see at #6351, I routinely faced this error for for 8 days now.

The bug issue heading might be equivalent to #6102? - but I am not sure whether it is the same issue.

How to reproduce: edit any text field and after a few seconds the exception shows up.

[Siedlerchr]

It's all the same underlying issue. Problem which makes it hard to debug, is that it's not occuring on Windows. But only on linux.

[ilippert]

Ok, thanks alot. Hm, I have no significant experience in tracing processes, neither in programming. In case you would recommend questions/debugging tasks, I would happily try to serve with relevant data.

[Siedlerchr]

I have just prepared a fix version at #6455 It would be nice if you could test that when it's ready

[Siedlerchr]

@ilippert Would be nice if you could test this version:
https://builds.jabref.org/pull/6455/merge/
(I also enabled debug symbols, so we now see line numbers as well in a potential stacktrace)

[ilippert]

the exception so far does not reoccur - in 10 minutes of testing. will report here if it does over the next days.

[ilippert]

yeah, but got this now after saving and writing this line:

Okay thanks that is a bit different now, but maybe related. Will look into it the next days

[Siedlerchr]

Just to clarify, you have entry editor open, at which tab?

[ilippert]

I have the entry editor open at a custom tab "annote".

I have now been working in the entry editor on a range of tabs and fields and the exception did not reappear.
