The compiler generates two errors for class Both below:

1. The return type is incompatible with IGeneric<Integer>.get(),
Generic<String>.get()
2. The interface IGeneric cannot be implemented more than once with different
arguments: IGeneric<String> and IGeneric<Integer>

Unfortunately, the editor hover and the status line only show the first message,
which is not very useful in this case. Either problems should be presented in
decreasing importance (here, error 1 is a consequence of error2 and therefore
less important), or the error 1 should be suppressed altogether (that's what
javac does).
 
class Both extends Generic<String> implements IGeneric<Integer> { }
interface IGeneric<B> {
	B get();
}
class Generic<B>implements IGeneric<B> {
	public B get() { return null; }
}

I'm not sure who's responsible for the ordering. Please move to JDT/Text if they
can solve this problem.
