Ooops ...Forgot to specify, the lock is held here:

at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.routeInternal(MessagingPostOffice.java:3133)

Note sure whey the thread-dump does not display that it is holding this lock...?


Many/many other threads then waiting for this lock ...e.g;
