> 5 nodes in JBoss Cache, pessimistic locking:
>   /a/b/c1
>   /a/b/c2
>   /a/b/locked
>   /a/b/c3
>   /a/b/c4
> And the node "/a/b/locked" is write-locked by another thread. Then try to delete entire node "/a/b". 
> Node.acquireAll successfully acquires write-lock on "/a/b/c1" and "/a/b/c2", but a TimeoutException occurs on "/a/b/locked" (which is expected).
> After this exception, locks on "/a/b/c1" and "/a/b/c2" are not released.
> Actually, Node.acquireAll shall return acquired locks, but in this case doesn't return anything but throws an exception. So, previously acquired locks are not in "cache.getLockTable()", and can't be released by UnlockInterceptor.
> TestCase attached.
