JMX Manager.manage in webapps #344

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 

It seems to me that if I use Manager.manage in a webapp it will break
during redeployment. When the webapp redeploys the JMX namespace is taken
and an exception is thrown like 

Exception: javax.management.InstanceAlreadyExistsException:
Myserver:type="com.google.inject.Injector

Is there a way to cleanup the jmx?

Obviously using a ServletLifeCycle listener and going through the jmx
domain unregistering each bean is one option.

In case it's not clear, this is the source of a memory leak and one of the 
reasons the webappclassloader cannot be garbage collected.

Yes, it would seem that if you tell JMX about a bean, you need to also tell JMX 
to stop handling the bean before you can tell it to handle another one of the 
same type.
