Okay, seems that we agree on "javaflow".

Yes, we have already talked with james strachan. And he seems to be
interested too. But for the first time I would start within Cocoon.

I think all java classes are capsulated in wrapper classes, and if these
classes suppport the continuation, then it should work.

Okay, then I start to commit the block.
