Hi,
I *think* you are hitting a variant of this issue (from 2004):
https://bugs.eclipse.org/bugs/show_bug.cgi?id=61568 - which is still not
addressed. It needs a large bunch of work doing and the workaround is so
easy that it hasn't become a priority. I know the workaround of
duplicating the advice (once for each variant) isn't ideal.
cheers,
Andy
