We need additional JRE serializers

I think a good start is to look what Kryo supports:

http://code.google.com/p/kryo/#Serializers
https://github.com/magro/kryo-serializers

Also, we will want serializers for the new the Java Time API , but I'm not sure if we should aim for the JDK8 version, or the backport.

And we might want support for some Guava classes TBD.
