Czukowski commented on NETBEANS-4623:
-------------------------------------
I wasn't sure about the Find text field length, I don't think I've tried to
find strings that are too long, at least not consciously (I might have pressed
Ctrl+F with multiple lines selected, but I think it's a special case as they're
not being pasted into the text field and the issue doesn't seem to reproduce
with multi line selection even in beta3). So I found the longest line in my
code I could and I tried instructions from [~junichi11] and it did break beta3,
although in a little different way: only the Find panel broke, other UI
elements seemed to work fine afterwards, and I didn't experience UI
unresponsiveness, I guess there must have been more than one way to trigger the
issue.
The same instructions did not break beta4 and the issue hasn't occurred during
the whole day of my usual work activities in beta4.

> Was testing 12.1 beta1 today, during my normal activity I noticed an error
> icon in the status bar at the bottom. The IDE was responsive and everything
> seemingly working so far.
> Upon clicking the icon, where the Notification panel would appear, only a
> blank space appears instead of it. If I try to open a file from Project or
> Files panels, similar things happen, editor tabs do open, but they are blank
> and gray.
> Other IDE dialogs (that are not panels) can still be open without issues.
> The only way I've found to get rid of the issue is to restart the IDE. It did
> happen a few times after that too, it wasn't clear which action has triggered
> the issue.

> See the attachment for the IDE log, this error can be seen repeated there
> multiple times.
