Java is used all the time, I even have a java program to write where I work.
the jvm is built into the worlds most used database, oracle, and in addition to that, you find it all over the place in enterprise applications.
of course, not sure what that success has to do with morphOS and consumer success.
The problem with java is not bloat, its the way it implements semaphores....many of these concerns have been overcome with faster hardware and new virtual machines.
so then you have complaints for these consumer systems, that its not really write once, run anywhere, the interface is a bit kludgy...
but you know, where it has found its home in enterprise computing its every good at, and there is no replacement right now... .NET doesn't even run on unix machines, for the most part.
I know some linux efforts, and the clr Microsoft ported to bsd...but for the most part, its really not there, and java won't be going away anytime soon.
I'm not sure having java on MorphOS is any kind of panacea, but if you use MorphOS and then 3 cheers for another option! Whats bad about that? It's great.
