Adrian, with some progressive changes in my AS5 trunk workspace, while running one of the tests in the test suite, the server log is filling up with the following exception (it is reaching something like 800MB in log size) ================= 2007-09-11 09:40:10,843 DEBUG [org.jboss.util.threadpool.BasicThreadPool] Timeou t monitor saw unexpected error java.util.NoSuchElementException at java.util.AbstractQueue.remove(AbstractQueue.java:80) at org.jboss.util.threadpool.BasicThreadPool.getNextTimeout(BasicThreadPool.java:475) at org.jboss.util.threadpool.BasicThreadPool$TimeoutMonitor.run(BasicThreadPool.java:593) at java.lang.Thread.run(Thread.java:595) ===================== I am still checking why this issue is happening. But I see that you are making use of a PriorityQueue and whose remove is supposed to be safe from any exception.

Sorry to have pointed at you. Scott has a nice comment also: ------- /** * A basic thread pool. * TODO: this port to jdk concurrent still needs to be tested. * * @author <a href="mailto:adrian@jboss.org">Adrian Brock</a> * @author Scott.Stark(a)jboss.org * @version $Revision$ */ ------- A combination of head, tail, cat, vi were needed to see through the maze of the logging - 900MB of server.log is not easy to deal with. :) So should I make the fix to this class and do a snapshot release for common-core? What should it be 2.2.2-SNAPSHOT?
