I can set the strictfp modifier on a method by
doing this:

MethodElement foo = getMyMethod();
foo.setModifiers(Modifier.STRICT);

This updates the source of my method correctly,
for instance, to 

strictfp void foo() {
}

However, if I now call getModifiers() on the
MethodElement, the returned modifiers don't
include the strictp modifier.
MethodElement.getModifierMask() doesn't include
the strictfp modifier either.

I believe this is a bug, since Modifier.STRICT is
a valid modifier for methods, and the strictfp
modifier should be returned by getModifiers().
