For the record, I am a C++ person, not a Java person. C++ is far and away my strongest language. Nevertheless, I believe that for general web app development, if you want something in the C++ family of languages, Java is more appropriate. At my startup we use a handful of languages for different tasks, C++ and Java among them.

I don't think anyone would have really jumped on the memory comment originally, but what made the thread asbestos-o-riffic however was the assertion that Java is inappropriate for a startup, which is, well, just plain silly.
