Description

If an acquire fails for an LVQ because the message has already been acquired by some other subscriber, the failed attempt causes the broker to crash. This is due to lack of proper bounds checking in Queue::acquire() for the LVQ case and was I believe introduced by http://svn.apache.org/viewvc?view=revision&revision=834172.
