Currently only SUNs javac fully supports generics. But we see no 
reason to make GNU classpath depending on this closed source thingie.
When Free Java Compilers are supporting Generics we will switch GNU 
classpath to officially use/support it.

We thought about doing it on a separate CVS branch of classpath. This 
way we can stay with our working implementation for non-Generics java 
compilers.

StringBuilder and StringBuffer are a bit different semantics wise.
There is a class in GCJ which has the java.lang.StringBuilder 
semantics. Perhaps we can reuse it.
