["Dave Brosius" <dbrosius@xxxxxxxxxxxxxxx>]

The weave task is only executed once, (I've added echo statements at the start and end of the weave task) and they are only seen once.

As for versions, i am using

java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Server VM (build 1.5.0_16-b02, mixed mode)


i'm not sure how i would know with Dynamic weaving. as i don't have the class files in that case.

That is very odd. Are you running the static weaver multiple times on the
same jar? What JVM are you using? Can you try using dynamic weaving and
see if you see the same duplication.
