[bv-dev] Method constraints and TraversableResolver contract

[Gunnar Morling]

Hi all,

working on the TCK, I'm wondering whether a BV provider should use
TraversableResolver#isReachable() and isCascadable()) to check whether a
validated method parameter or return value may be accessed/traversed.

I think checking for cascadability might make sense, but I'm not so sure
about checking for reachability; can e.g. be a parameter not reachable?

If any of the checks shall be done for method validation, we need to update
the TraversableResolver contract (section 4.6.3) which
currently explicitly speaks about properties and is limited to the element
types FIELD and METHOD.

WDYT?
