Sorry for late reply, I was abroad.
I've added MoDisco newsgroup to the discussion. Maybe they are interested.

For know I am using MoDisco J2SE5 metamodel/discoverer with small
changes (I have removed ATL dependencies, as I don't use J2SE5 -> KDM ->
UML, nor ATL).

MoDisco have a bit newer (and as they claim better) model/discoverer , thus I will probably move to it
one day. The metamodel is not much different, so it should be easy.

I have working but incomplete templates in Eclipse M2T Xpand for
generating Java code from J2SE5 metamodel. They are not "production
quality". As I said before they do not handle comments, generics and
some basic constructs are missing. It is possible that they have some
errors, as they was not tested much. Nevertheless they works for me ;)

I can share them, preferably as open source contribution.
But, AFAIK MoDisco plans to develop some kind of serialization for Java
model. I am not sure will it be Java or Acceleo based serialization though.

I don't know that, you can ask on EMF forum.
