problems with aj and verbose

Hi from a aj newbie:

I have modified aj by setting –Daj.weaving.verbose=true, but no logging messages are forth coming. 

Worse, if I set

-Dorg.aspectj.tracing.enabled=true  –Dorg.aspectj.tracing.factory=default –Dorg.aspectj.debug=true

then I get …

Error occurred during initialization of VM

java.lang.Error: java.lang.IllegalStateException: recursive invocation

I am using sdk1.4 (although this happens regardless of the sdk version)  and aj1.5 and aj1.6

So my question really is: how do I get verbose output from the weaver if using aj (i.e. using sdk1.4 and NOT setting javaagent).

Thanks.
