Back to this issue, the commits to branch 2.0 of the TCK are fine.
However, as I continue working through our list of TCK failures, I
managed to trigger another problem with this same composed constraint.
It is explicitly applied to RETURN_VALUE of Person.getAge(), but the
@CustomComposingConstraint is applied to PARAMETERS, which by my
current cut of code runs afoul of the requirement in section 3.1.1.4
that it is illegal to specify PARAMETERS on an executable with no
parameters.
