@nonglobal,
please give a bit more details about reproducing the error. So, you open Jabref, click on an article, and enter a new word in "Author" field, right?
I don't see an error on my computer. What kind of entry do you have?

[AEgit]

JabRef 5.1--2020-04-29--7219e36
Linux 5.3.0-51-generic amd64
Java 14.0.1

I cannot reproduce this issue.

[ilippert]

not sure, whether this is helpful - but in the log entry I get the sense of autocompletion being involved, similar to #6344 - might that be the case?

@nonglobal,
please give a bit more details about reproducing the error. So, you open Jabref, click on an article, and enter a new word in "Author" field, right?

Yes. Adding a new entry in the author field and only in author field.
It's occurs with autocomplete enable or disabled.

I don't see an error on my computer. What kind of entry do you have?

It's occurs in any kind of entry (article, book, etc.).

Yes

[nonglobal]

Same error in the "linux portable" version.
Possible Java instalation issue?

[Gena928]

Maybe. Can you reinstall it?
I have Mac computer and I can't reproduce error. I.e. everything works fine and no error messages appear.

[Siedlerchr]

@nonglobal Have you tested the latest development version? https://builds.jabref.org/master/

[nonglobal]

@nonglobal Have you tested the latest development version? https://builds.jabref.org/master/

Yes: jabref-5.1-1.x86_64.rpm
Unfortunately, i got the same error.
Same thing with portable linux version.
Maybe an error in my Java installation?
