Yeah indeed a deadlock inside the OpenJPA code is the root cause of the problem (org.apache.openjpa.kernel.BrokerImpl#lock()). I just commited a fix regarding this, so let's keep an eye on this test by the next builds. Following a screenshot of the proven deadlock through jconsole:
<http://camel.465427.n5.nabble.com/file/n5741448/Screen_Shot_2013-10-12_at_11.02.58_PM.png> You can enforce the deadlock if you would make use of a high log level (log4j.properties), e.g. TRACE instead of just INFO.
