any of them write a more successful language than Java? or how about Visual Basic even? For all the complaints, at least Java moved programming technology to another level on a massive scale, lest we all be complaining about C/C++ still.
Java seems to be mostly a step backwards from C++ in terms of expressiveness, with kludges here and there to hide the fact. Because the kludges are very slow, I have had significantly less luck optimizing Java than C++.
