Re: [aspectj-users] method <clinit>code size too big problem when weavin

["Eric Bodden" <eric.bodden@xxxxxxxxxxxxxx>]

You mean you have 3200 pieces of advice? Or 3200 joinpoint shadows? In
the former case, your code is wrong, I suppose, and in the latter
case, it seems strange that 3200 JoinPointStaticParts are being
created.
