RE: [aspectj-users] How do I write this aspect.

["Pankaj Dhoolia" <pankaj.dhoolia@xxxxxxxxxxxxx>]

Thanks a lot for such a quick response to Ramnivas, and thanks a lot to
the folks at AspectJ in general, for providing such a powerful tool.
With this I am now able to instrument thirdparty jars to fix bugs in
them for a workaround while I await a patch from their support.

cheers,
pdhoolia

Try this:

Long around(String param) : call(Long.new(String)) 
                            && withincode(RType X.foo(..))
                            && arg(param) {
    return proceed(<your-string-here>);
}
