Uncaught exception

[jmdesantos]

JabRef version 5.0--2020-03-06--2e6f433 on Ubuntu 18.04

• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Tested with development version 5.1: it is the same, and so many warning windows open that freezes the computer.

Upon opening, scrolling down the entries after a few seconds multiple windows titled "Uncaught exception occurred in Thread[pool-9-thread-1,5,main]" appear, and sometimes continue to appear to the hundreds making the application unusable.
My database have 13064 entries.

Steps to reproduce the behavior:

1. Open the database
2. Scroll down the entry list
3. Exception message windows start to appear.

I can confirm the exact same behavior but it is not happening now. It also always happened at the same location
when scrolling down. It is not happening with the last development version. Did you check it? I had the feeling
it was something to do with translation of title stings with some latex combinations causing a problem.

Yes, I tried w the development version too. It opened so many windows that my computer froze. Regards, Juan Manuel

Could you please check in your bib file if you have save actions defined? Open the bib file with a text editor and at the end of the file there is something like @Comment{jabref-meta:... which lists save actions. Please remove that line and try again with the latest dev version
