[aspectj-dev] trouble with load-time weaving

I'm having major trouble geting load-time weaving to work in Eclipse.

I lifted a simple example from
Boy/Girl/Kissable/Main with aspect Teacher.

If I run with load time weaving, I get a bunch of errors, a subset of which I included at the end of this message.

The most puzzling thing is that it tells me that classes were already woven and were not built in reweavable mode, but if I put -Xreweavable into the <project> -> Properties -> AspectJ -> Non standard compiler options field, I get a message that -Xreweavable is turned on by default.

Any ideas on what I could be do to make the errors go away?

I am using Java 5 (compiler compliance level set to 5 in the workspace configuration).

I have
   -javaagent:<my path to>/aspectjweaver.jar
set in the <run> -> Arguments -> VM arguments field.

I am running on Linux, kernel

I am running Eclipse 3.1.2.

I have AspectJ 1.5.  aspectjrt.jar is on my CLASSPATH.

A small subset of the error messages:
java.lang.ClassCircularityError: org/aspectj/weaver/UnresolvedType

(end error message output)
