-----------------------------------
Summary: JMX connections not being closed
Key: JAMES-1534
URL: https://issues.apache.org/jira/browse/JAMES-1534
Project: James Server
Issue Type: Bug
Components: CLI
Affects Versions: Trunk
Environment: Linux
Reporter: Phillip Odam
The JmxServerProbe class doesn't offer any way to close the JMX connection.
This doesn't present itself as a problem in how Apache JAMES code uses this
class. However in the case where long running apps use this class, out of
memory errors can occur since objects aren't GC'd due to the hanging connection.
To address this I'd suggest making the following changes
- have the interface ServerProbe extend java.io.Closeable class
- make locally declared JMXConnector jmxc variable (in JmxServerProbe's
connect method) to be a private member
- make the private member MBeanServerConnection mbeanServerConn be local to
the connect method (clean up)
- implement close method in JmxServerProbe class that calls JMXConnector's
close method
