Instead of the switch/case statement, can't you use
`PrimitiveArrayTypeInfo.getInfoFor(Class<X> type)`? Seems simpler.
Also, this is a good change to be backed by a Unit test case, rather than
an Integration test case.
I really think that such changes should be guarded by more fine grained
tests (Unit Tests(, rather than the "big hammer" kind of test (have a
distributed program that uses this). Out testing time goes through the roof
otherwise.
I fund that unit tests are a cycle or two more work to write, but typically
also get you thinking better about what cases the tests should cover.
