You are making a mistake of talking about tools when we are discussing programming languages. I have seen most people make that mistake with .NET platform. Java programming language isn't Java platform. In fact, as a Lisper, you should know better to dissociate the tools from the platform because Lisp is so fragmentated.

J++ was a Microsoft independent implementation of Java programming language. Also Java used by Android is an independent implementation of Java programming language. It doesn't contain tools which are shown on the Java platform architecture diagram I pasted on my previous comment.
GC isn't part of Lisp. Never was. Never will. It was invented as a tool to be used with Lisp. In fact, some Lisp dialects don't even have garbage collection.

I was exxagerating to emphasize my point.
