FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
1. Run the MBeanServer in Linux
2. Register an MBean to the server (Let the MBean method takes a custom object as a parameter)
3. Invoke that MBean from a client using RMI connector

For every invocation, the OrderClassLoader reference is getting leaked .

The leak happens when umarshalling happens in the RMI layer




REPRODUCIBILITY :
This bug can be reproduced always.
Submitter writes:

During the unwrapping of the object
The following line is getting executed (From javax.management.remote.rmi.RMIConnectionImpl.java

private static <T> T unwrap(final MarshalledObject mo,
                                final ClassLoader cl1,
                                final ClassLoader cl2,
                                final Class<T> wrappedClass)

{
// ....
return unwrap(mo, new OrderClassLoaders(cl1, cl2), wrappedClass);

}

When i profiled .. i found the instances that are created here are not getting garbage collected.. even after full GC.

This happens only in linux... when i tried the same in windows then i am not able to see the references in the profiler ... they are getting garbage collected ...

 The MBean that i registered with the JMX server is taking some custom object
a method like
public void myMethod(MyObject obj)
{

}
