Is this multi-thread safe? - calling methods on the proxy object returned by JmsProxyFactoryBean

[madhav]

Is it possible to call methods on the object returned by JmsProxyFactoryBean.getObject() from multiple threads simultaneously? Do the method calls get serialized somehow?
Is there any multi-thread synchronization somewhere down the line?
If the receiving end-point of the method call (a different process) dies, will there be a release of synchronized locks somewhere?
