Description David Akehurst CLA 2007-09-07 09:20:05 EDT 
Build ID: I20070625-1500

Steps To Reproduce:
This code compiles in versions 3.1 and 3.2 of eclipse but not in version 3.3 or 3.4, 

public class Test {
	public <A, B> void func(Class<? extends XX<A, B>> cls) {}
	public void func() {
		func(XX.class);
	}
	class XX<A, B> {}
}

Comment 1 Philipe Mulet CLA 2007-09-07 09:55:25 EDT 
This was a bug which got resolved in 3.3. Basically, the compiler should have been rejecting such code. This results from the fact Class<XX> is not assignable to Class<? extends XX<A,B>>.

Basically raw type arguments are not compatible with parameterized forms of type arguments.

Invalid, btw javac5 (1.5.0_12-ea) and javac6 (1.6.0_03-ea) both agree with us.

Added GenericTypeTest#test1157
