Subject Re: java.util.ConcurrentModificationException during DeploymentScanner work
Date Sat, 13 Dec 2003 18:38:01 GMT
This problem is inside of MX4J.  My guess is it is because we are using  
an old build of MX4J.  I'm going to try to get MX4J and cglib upgraded  
to the newest release (beta) or CVS HEAD this weekend.
