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.

What was the original email that was sent to Gerald Sussman?  The one that started the unscientific and ultimately destructive meme.

We need to do the same for more people.  RMS, Abelson, Linus Torvalds, even [spoiler]Mat Dickie[spoiler].  We'll have a /prog/ celebrity thread.  Bring them all to our wonderful pit of cancer.
