Obvious question would be why.  Seems as if there are some technical
reasons.  As I understand them, totally hearsay, they are:

  Axion: faster startup time,
         great for unit testing
         each transaction has its own copy of data
         Oracle compatible SQL dialect (sequences, etc.)

  Derby: XA support
         multiple concurrent users
         transactions use locking
         DB2 compatible SQL dialect

Is that correct?  Anything else?  Both are good, but with some differences,
so it might be helpful to have a comparison matrix if there are knowledgable
people who would contribute to it.
