Re: [aspectj-users] Generic aspects

["Andy Clement" <andrew.clement@xxxxxxxxx>]

The logs date is 20080511215715 and the build date is 20080510020449
so on this occasion the
build machine has gone bad - uploading the changes list but not the
build with the fix in.
Wait for a build dated after the bug was closed, should be later today.

Andy.
