-----------------------------------------
Summary: memory leak when using STOMP protocol
Key: ARTEMIS-741
URL: https://issues.apache.org/jira/browse/ARTEMIS-741
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Stomp
Affects Versions: 1.4.0
Environment: JDK 8, Apache Tomcat server or standalone app, Linux or
Windows
Reporter: Mitchell Ackerman
ArtemisMQ exhibits a memory leak when using the STOMP protocol.
Steps to reproduce:
1. Configure a server with a JMS topic, my example uses an EmbeddedJMS server
2. Connect to the server using the STOMP protocol
3. Subscribe to the topic with a selector
4. publish some messages to the topic that match the selector (this step may
not be necessary)
5. Unsubscribe from the topic
6. publish some messages to the topic that match the selector
The messages published after the unsubscribe are retained in a QueueImpl
object, messageReferences queue and are never cleaned up unless the client
disconnects. The QueueImpl object has 0 Consumers (ConsumerList size is 0),
and the QueueImpl object retains the filter from the subscription.
