Description

If asyncStartup of ActiveMQ is used (for a failover broker scenario where brokers used shared storage), the shutdown of a backup broker will hang. So, Geronimo server shutdown does not complete. This is really an ActiveMQ problem. However, I think we should work around the problem for now. This seems to be a problem with AMQPersistenceAdapter only. Doesn't seem to be a problem for the KahaPersistenceAdapter.

Here's where shutdown gets hung up:
