-----------------------------------------------------------------
I made a similar patch against 4.0.3 that we are testing out now, that tries to
improve the attached patch(new patch attached):
- Properly signal that lock was removed from map using notifyAll
- Replaces the map with a set, and simplify/fix logic in the check. I think its
a bit easier to understand at least.
It also:
- Adds registerAsParallelCapable
- Makes bundleclassloader and bundleclassloader5 static (I just used intellij's
'make static' to get this done)
Still unresolved:
- Handling interruptedexception.
Let me know if you can review it, or if I should try produce a patch against
trunk. Btw, if you have any stress tests that can easily reproduce the deadlock
issues, that would also be very helpful. We are able to reproduce it, but it
requires a lot of effort in terms of patching our system.
Thanks
