In WAS with Java 2 security enabled, the library requires execute permission on ALL FILES. Although it seems that the chmod action is not required(at least in my case) it is in place. It might be a good idea to make it optional so that the ALL FILES permission will not be required.

Seems to be happening because of an unrequired chmod?

Why is the exception caught but not logged? Can this be removed?
