#4134 jEdit becomes unresponsive to key presses (LSP plugin?)

[Damien]

I've been seeing some strange behavior within jEdit recently while trying to use it to work on the LSP plugin. Shortly after beginning work, jEdit becomes completely unresponsive to my key presses, and I cannot for the life of me figure out why.

• This behavior normally kicks in as a result of opening the search-and-replace dialog, though I have seen it with other popups too (like Help->About jEdit...). Until I do that, typing works just fine.
• Mouse interaction within jEdit still works.
• My keyboard still works outside of jEdit.
• No plugin appears to be responsible, since I'm able to reproduce it with no plugins loaded.
• No errors appear in the activity log.
• I have seen this with both Java 11 and Java 17.

This is tested with jEdit 5.6.0 running on openSUSE Tumbleweed.

Anyone have any tips on how to debug this further? I really have no idea what's going on, and it's making jEdit borderline unusable.

Does view - scroll and center caret make the problem go away?

Well, now that I've reported the problem I can't seem to reproduce it. I will certainly give that a shot if I run into it again, though.

I think that this is what occasionally locks up my keyboard also.  In my

case, the keyboard becomes unusable in all open applications, so I have to
reboot to recover.

I've had this problem when opening too many files at once. One of things that's great about jedit is the infinite divisibility of the editor window. I used to be able to open 15 separate windows. By reverting back 5.4 the problem exists but goes away if I close a file. In 5.5 & 5.6 the app needs to closed and reopened.
