Hi All,
Could somebody please tell me how to handle concurrency issues in Groovy?

At this point, it's exactly like you would handle concurrency in Java.

A good workman is known by his tools.

The best thing about Groovy concurrency is that Closure implements Runnable. So you can very easily kick off a process running in a new thread:

You should see the parallel printouts, something like this:

Thread[Thread-15,6,main]: 1
Thread[Thread-16,6,main]: 1
Thread[Thread-15,6,main]: 2
Thread[Thread-16,6,main]: 2
Thread[Thread-15,6,main]: 3
Thread[Thread-16,6,main]: 3
Thread[Thread-15,6,main]: 4
Thread[Thread-16,6,main]: 4
Thread[Thread-15,6,main]: 5
Thread[Thread-16,6,main]: 5
