Primitive rendering in Sun's WTK2.3 reference implementation bugged!!?

[Abuse]

I've just been writing some device profiling code,
and have discovered to my surprise the following methods don't honour the current clip rectangle!? :-

drawRoundRect, fillRoundRect, and drawArc. (strangly fillArc works as it should)

I'm going to test the latest WTK2.5, but I can't imagine the behaviour of such a core method would have been altered.

I'm beginning to understand how so many handset implementations can't even do something as simple as a drawRect correctly!!
