A failure in this new test also means that the committer didn't properly test the new method.
I'm merging feature/GEODE-5183 to develop today. This adds a new test
to AnalyzeSerializablesJUnitTest and its subclasses that will complain
if a toData/fromData backward-compatibility method doesn't correspond to
a valid Version. This is an effort to aid folks in creating this kind
of method.
