Hi,

For the AspectJ 1.5.0 release, we are not planning to allow matching
upon parameter annotations, which is what you are using in your
program.  See the developers notebook here:

http://eclipse.org/aspectj/doc/next/adk15notebook/annotations-pointcuts-and-advice.html#d0e1421

which explains:

---
Package and Parameter Annotations

Note: A previous design allowed package annotation patterns to be
specified directly in type patterns, and parameter annotation patterns
to be specified directly in method and constructor signature patterns.
Because this made some pointcut expressions hard to read and
understand, we moved in favour of the design presented below, which
also has its drawbacks. Matching on package and parameter annotations
will be deferred until after the 1.5.0 release so that we can gain
more understanding of the kinds of uses AspectJ users are making of
annotations in pointcut expressions before commiting to any one
approach.

regards,
Andy.
