Hanging forever on database bootup during unit testing
I have a bunch of unit tests that I run as a suite. The first test that
tries to boot up the Derby database hangs, with the CPU spiked at 100%.
When I stop the process, here is where it is stuck, repeatedly (see stack
trace below).
When I run the same test by itself, it's slow to boot, but it doesn't hang.
The database is small, it actually has no rows in it.
Any ideas? Should I be reverting back to 10.4? I seem to be having a lot of
issues with 10.5 and booting/shutdown. This is a serious problem; if it
happens in production it will be a Very Big Deal.
Thanks,
David

Hm, OK, thanks for the tip, it's good to know what direction to look into.
I'm not on that dev machine now, and I have to see what Eclipse is using,
but it's a version of Java 6 on XP.

It looks like it is the jvm having trouble just extracting from the jar
file, so I am doubtful that changing your Derby version would help. I
am curious the platform and jvm versions and if this problem began with
with a change of either.
