Description

I've seen CombinedTest fail twice this evening with the following stack trace on java-bdb.0-9-1. I don't think I've ever seen the test fail before.

Whilst CombinedTest itself seems of questionable value, the Qpid client stack trace (java.lang.IllegalStateException: dispatcher is not started) seems potentially worrying as the client code (org.apache.qpid.test.unit.client.forwardall.Client) has called connection#start() so the dispatcher should be running.

Examining the logs I see:
