How to prevent concurrent execution of scheduled methods in AS 7

[aolenev]

Hi,

I have a method annotated as following:

@Schedule(second = "*/10", minute = "*", hour = "*", persistent = false)
public void run(){
    // some code here
}

It runs every 10 seconds as expected, but if I suspend thread inside run() method in debug mode JBoss triggers run() method invocation in another thread in parallel.

So the question is: how to prevent parallel execution of scheduled method? What should I do if I need single threaded scheduling?

You might use a @Singleton Bean, in this case the execution will be delayed and aborted with an Exception after a timeout.
