Fix infinite recursive loop DO NOT MERGE

FindBugs description:

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.

Note: Checked into AOSP. Cherry-picking for mr1.1.

Issue #7621806 IntProperty has infinite recursion bug
