Re: [aspectj-users] Capture one annotated parameter amongst many

[Andy Clement <andrew.clement@xxxxxxxxx>]

Me again,

I raised it as https://bugs.eclipse.org/bugs/show_bug.cgi?id=293203
and just committed the fix.  It will be in an AJ dev build today then
an AJDT in a few days.

(This is the problem of (..,String,..) matching and not (..,@NN (String),..) )
