Re: [ jEdit-users ] jEdit gets stuck in I/O loop (maybe)

[Vampire <Vampire@jEdit.org>]

Looks much like a BufferTabs bug for me.
Buffertabs catches and logs an ArrayIndexOutOfBoundsException.
I'm not sure this is related to the total freeze of jEdit though, but it
is anyway a bug that should be reported against BufferTabs, even if it
is independent from the UI hang.

Thanks
Vampire
