Fix infinite recursive loop

There is an apparent recursive loop at IntProperty.java
in method set(Object, Integer)

This method unconditionally invokes itself. This would seem
to indicate an infinite recursive loop that will result in a stack overflow.

This was brought over from out original JB branch.  Somehow, this got
overlooked, and never made it into JB42.
