There is no reason to expect that distinct invocations use distinct threads.
The invocation entry point is responsible for establishing the thread
context. In this case the try{...} finally{...} of the JRMPInvoker has
to clear the thread locals if it wants to limit the context to the invocation
lifetime.

Subject: [JBoss-dev] ThreadPooling in JMX? Its broken
> Ok, I was doing some coding and found that my ThreadLocal variable was the

> TESTCASE:

> 1. remotely invoke on method test1 - this sets testit ThreadLocal variable

> 2. return from remote invocation
> 3. remotey invoke on method test2 - this just prints out value of testit
> ThreadLocal variable. It will still be hello!

> How the hell can you clear ThreadLocal variables if you are thread pooling?
