Comment 1 Anton Leherbauer CLA 2009-03-26 07:56:17 EDT 
Moving to JDT Core.
Comment 2 Kent Johnson CLA 2009-03-26 12:17:06 EDT 
This has been fixed in 3.5

FYI, the problematic method is :

interface J<T> extends Comparable<J<T>> {
	int getSize();
	T getField();
}
class X {
	<T extends J<?>> int x(T t1, T t2) {
		return t1.compareTo(t2);
	}
}

This compareTo() call compiled without error in javac 1.5, but now reports an error with javac 6.0.

Our compiler also reports an error in 3.5
Comment 3 Kent Johnson CLA 2009-03-26 12:23:46 EDT 
Actually this was fixed in 3.4.2
Comment 4 Jay Arthanareeswaran CLA 2009-04-28 02:08:36 EDT 
Verified for 3.5M7 using I20090426-2000 also.
