Description Philipe Mulet CLA 2005-06-20 17:50:37 EDT 
Build 3.1rc3

The following program should compile ok:

interface I {
	void clone();
}

In 1.4 mode, it must complain as it does; but in 1.5 mode it must tolerate this
situation.

Also see bug 94759 for closely related issue in same area.
Comment 1 Philipe Mulet CLA 2005-06-20 17:54:57 EDT 
Slight modification of the previous code yields an error against J which doesn't
make much sense to me, as J doesn't implement the interface, it simply extends it.

interface I {
	@Override void clone();
}

interface J extends I {
}

Fix will not be ready for 3.1.1, removing target milestone "3.1.1"
Comment 3 Kent Johnson CLA 2005-10-18 18:24:22 EDT 
Added MethodVerify test074

Released into HEAD and 3.1.2 stream
Comment 4 Philipe Mulet CLA 2006-01-10 07:14:11 EST 
Better testcase:
interface I {
	void clone();
}
interface J extends I {
}

should only yield a warning on I (cannot be implemented), but no error on J.
Also compliance doesn't seem to be involved. We should always behave consistently throughout compliance modes.
