I notice you've ripped this logic out of the InvocationContextInterceptor in branches/4.2.x

http://fisheye.jboss.org/browse/Infinispan/branches/4.2.x/core/src/main/java/org/infinispan/interceptors/InvocationContextInterceptor.java?r1=2273&r2=2323&u=3#l45

Note that this is incorrect since, as I pointed out, you will miss exceptions thrown between the InvocationContextInterceptor and the LockingInterceptor.

This code was committed before this discussion to take place. I needed it in because couldn't work on DLD without it). 

It wil be addressed in  ISPN-629
