Claus Ibsen created AMQ-4033:
--------------------------------
Summary: AMQ Broker - Uses custom RMIServerSocketFactory class
which cannot be unloaded due socket reuse
Key: AMQ-4033
URL: https://issues.apache.org/jira/browse/AMQ-4033
Project: ActiveMQ
Issue Type: Bug
Components: Broker, JMX
Affects Versions: 5.6.0
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Priority: Minor
When embedding ActiveMQ Broker in a container, such as Tomcat or others. And if
you have JMX enabled on the broker, then a RMI registry is created to allow
JMX/RMI over TCP.
This uses a custom RMIServerSocketFactory that gets enlisted into the JDK RMI
registry. But when you undeploy the AMQ broker, there is no API in the JDK to
unregister your custom RMIServerSocketFactory class.
And therefore the JDK (system class) has a strong reference to the custom
RMIServerSocketFactory, which prevents the container classloader to fully
unload all classes.
Disabling JMX on the broker, allows to unload all the classes.
