Eclipse (3.1M2) with Java 5

Anyone tried using Eclipse with any of the new Java 5 features?

I have 3.1M2 installed and turned on the 1.5 compiler settings for eclipse.
That got rid of a few errors, like complaining about the

import static java.lang.Math.*;

However, when i try to use any of the methods or fields from the Math class it still complains saying
that it can't be resolved. For example.

xVelocity = cos(direction) * speed;

will say that method cos cannot be resolved.
i'm not sure i really ever care to use static imports, but i'm just testing to see if its working and its sort of doesn't
appear to be.

i guess my biggest problem is that i see no clear documentation or forums for eclipse on the current status.. or a roadmap.
i'm sure there is one hidden on eclipse.org, but that place is a confusing mess if you ask me.


any luck?
