Hard to believe but there is no way to do this through listener. After I 
could not find a way to do it I even posted a question on testng-users 
and got a recommendation from Cedric to nullify all instances from a 
@AfterClass method in superclass.

I also found that I was wrong regarding invocation of @AfterClass 
methods:) As long as you do not override @AfterClass method it *will* be 
invoked starting from the leaf all the way up through ancestors. I 
created a superclass called AbstractInfinispanTest with 
nullifyInstanceFields method and made AbstractInfinispanTest superclass 
of all test classes. Works as a charm and guranteed no more leaks!

Let me know if you have any reservations to this change.
