Hi Sergio,
We're currently having an issue on myxwiki.org with some thread
deadlock (caused by Velocity it seems). We're trying to fix the
problem. Try again a bit later and hopefully it'll work.
Sorry about that.
Upgrading to Velocity 1.6.2 seems to help, but more testing time is
needed to ensure that.
Later today I found another deadlocked appearing in
java.util.concurrent.LinkedBlockingQueue, called from JBossCache, so now
I'm trying to see how an updated JBossCache library behaves, although
the threaddump suggests an impossible halt on the following line in the JDK:
last = last.next = new Node<E>(x);
What could possibly be wrong with this line? Unfortunately this was in a
CS section, so all the other threads were waiting...
