svn commit: r712467 - in /tomcat/trunk/java/org/apache:
catalina/connector/MapperListener.java tomcat/util/http/mapper/Mapper.java
Author: markt
Date: Sat Nov 8 17:57:34 2008
New Revision: 712467
URL: http://svn.apache.org/viewvc?rev=712467&view=rev
Log:
Fix for https://issues.apache.org/bugzilla/show_bug.cgi?id=42707
I debated adding the addContainerListener() meethod to JMX. I'll leave it a little while for people to comment on this (or anything else) before I propose this one for 6.0.x.
