[Jon Henry]

Public bug reported:

Version info:
Description:    Ubuntu 12.04.2 LTS
Release:        12.04
Installed: 7.0.26-1ubuntu1.1

Since upgrading from Ubuntu lucid to precise and Tomcat 7.0, our
application periodically logs an exception like this to catalina.out:

Feb 12, 2013 3:18:40 PM org.apache.coyote.ajp.AjpAprProcessor process

This bug was reported and fixed upstream as of Tomcat 7.0.28
(https://issues.apache.org/bugzilla/show_bug.cgi?id=53119). Is there any
chance this fix could be cherry picked into the Ubuntu precise branch?
The 3-line patch is here:
