My Java method is :-

private static Object workingProducer() throws InterruptedException {

  String producerThreadName = Thread.currentThread().getName();

  System.out.println("Producer Thread..." + producerThreadName);

  String testMsg="Hello world";

   int messageCount = 0;

   while (true) {

   blockingQueue.put(messageCount++);

  System.out.println("Thread " + producerThreadName + " inserting " + messageCount + " into the blocking Queue");

   // sleep for 1 seconds so that we can see in console how threads are working
   Thread.sleep(1000);

  }

}

My .btm file is :-

RULE run producer then halt but consumers continue to run

CLASS ThreadInteraction

METHOD workingProducer

AFTER WRITE $producerThreadName

BIND testingMessage = $testMsg;

IF true

DO traceln($testMsg)

ENDRULE

When I run this on debug (-Dorg.jboss.byteman.verbose) , it shows me

RuleCheckMethodAdapter.checkBindings : invalid local variable binding $testMsg checking method workingProducer()Ljava/lang/Object;

But you can see testMsg variable name exists in above private java method.

What is wrong in the usage?  Please provide me the right usage is anything is wrong.
