JOIN US!! persons who hate JAVA!!

Seriously though, you gotta be into S&M if you decide to develop something in Java yourself and you'll be doing part of the job.

The problem with Java has nothing to do with any technical issues. It's faster than a good many languages since it is compiled to bytecode rather than just read from a script.

The problem is it's a poorly designed language that's no fun to program in. It claims to be an object oriented language but it's possibly the worst example of OO I've seen. Well C++ isn't too good at it either. It has a primitive type system that is incompatible with the object system. Wanna use ==? Go ahead and use it on your ints, but it's practically useless on your strings. Ditto switch/case. Wanna define new operators for your classes? Sorry. Want polymorphism? You can have it, but get ready for lots of disgusting type casts!

Java is pretty much singlehandedly responsible for giving OO a bad name. Try something like Ruby or Smalltalk if you don't believe me.
