AFAIK sun has quite strict rules about claiming compatibility with any 
of their Java products. Basically, you can't do it, unless you shell out 
big bucks for a license to their code. But I may misunderstand what you 
want to say.

It's just that all those java'ish runtimes are all somehow different in 
my experience, so trying to put some kind of 'it's all mutually 
compatible java' cover on it doesn't really fit. A 'abstract 
machine'-'runtime' mapping only works as long as there are only a few 
runtimes available. In java's case, those days are long gone, and the 
number of options is quite huge, so fitting all of them under the same 
cap is quite complicated, if not impossible. I assume that in few years, 
c# will have the similar problem ;)
