Description Frederic Fusier CLA 2004-09-21 09:41:01 EDT 
Using build I200409210010.

For following test case:
public class Generic<T> {
	T x;
	<U extends T> T foo(U u) {
		if (u == null)
			return this.x;
		return u;
	}
}
compiler warns "U" in <U extends T>: "Illegal forward reference to type
parameter T" altough parameter T has been already defined...
