why does java suck?

I've noticed in the short time I've been reading this board that there's a lot of java bashing, so I was wondering why people actually think it is so bad. I'm no java fan, but I've used it for some stuff before and it didn't seem terrible to me. An argument used to be that it runs slow as a guro-fied loli, but they've improved a lot in that aspect.

Please give good reasons, rather than stuff like "it's for certified professional consultants" or whatever you guys say.

Java is bad because it's slow. How come it's slow? It uses byte code. Meaning, you have to basically "compile" the program every time you run the thing. Don't believe me? Go play Lineage II on L2J, and see how efficient it is. If Java was so great, databases and servers would be running off the thing. But of course, programmers are smart, so they use the stuff that is known to work. C++, C, Assembly, etc. AKA the real languages.
