Description

Over on HBASE-9834 LarsH suggested:

I now wonder how we can write a test to catch these.
Maybe generate a file will all kinds of a objects, save that. Then
read that back
regenerate and make sure it's identical
that way we ensured that neither readFields nor write has changed.

We can find all readField/writeFields in the code and generate files for use comparing changes against serializations produced by the previous release.
