Minor Description
I've noticed issues with distributed transactions (XA) on karaf when using ActiveMQ with JDBC storeage (postgres). After some time (it isn't deterministic) I've observed that on database side 'idle in transaction' appeared (it's other schema than used by ActiveMQ). After debugging it seams that the reason why transactions are hanging is ActiveMQ and org.apache.activemq.transport.FutureResponse.getResult method that waits forever for a response.
