Justin Bertram updated ARTEMIS-5874:
------------------------------------
Description:
A deadlock can occur when the broker services a STOMP {{DISCONNECT}} frame with
a {{receipt}} header at the same time the corresponding connection is closed by
the broker (e.g. due to inactivity). Here's the relevant stack-trace:
{noformat}
Found one Java-level deadlock:

Found 1 deadlock.{noformat}
was:
A deadlock can occur when the broker services a STOMP {{DISCONNECT}} frame with
a {{receipt}} header at the same time the corresponding connection is closed by
the broker (e.g. due to inactivity). Here's the relevant stack-trace:
{noformat}
STOMP protocol can hit a JVM deadlock. Here are the key details:
* DISCONNECT frame sent to the broker on valid STOMP connection
** with a "receipt" header
* At the same time, Netty reports a disconnect (call goes to
{{{}org.apache.activemq.artemis.core.remoting.server.impl.RemotingServiceImpl.connectionException{}}})
Deadlock is reported by {{jstack}} or {{jcmd ... Thread.print.}}
The cause is 2 locks being acquired in different orders by separate threads.
Here are the top of the calling stack for the 2 deadlocked threads:
* at
org.apache.activemq.artemis.core.protocol.stomp.StompProtocolManager.send(StompProtocolManager.java:203)
* at
org.apache.activemq.artemis.core.protocol.stomp.StompConnection.destroy(StompConnection.java:225)
