It is causing problems in our log reports.
May 15, 2010 11:21:58 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
SEVERE: A web application appears to have started a thread named [Session Monitor] but has failed to stop it. This is very likely to create a memory leak.

SEVERE: A web application created a ThreadLocal with key of type [org.icefaces.application.WindowScopeManager.CurrentScopeThreadLocal] (value [org.icefaces.application.WindowScopeManager$CurrentScopeThreadLocal@38d748]) and a value of type [java.lang.String] (value [psg99f5dt2]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.

Refactored WindowScopeManager to use a request attribute instead of the thread local in order to associate the window scope IDs to the incoming requests.
The 'Session Monitor' thread was removed by the fixes for ICE-5756.
Verified as successfully during nightly regression test on Glimmer revision# 21838.
Testing with Mojarra 2.0.3 shows this issue has returned...

Glimmer revision: 21849
Server: Tomcat 6.0.26
Browser: FF3.6
Logging looks messy. The following message is output for all the test cases:
6-Jul-2010 9:10:25 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: A web application created a ThreadLocal with key of type [null] (value [com.sun.faces.util.Util$1@d631b4])
and a value of type [java.util.HashMap] (value [{com.sun.faces.patternCache={ = }}]) but failed to remove it when the web application was stopped.
To prevent a memory leak, the ThreadLocal has been forcibly removed
This message is due to the new Mojarra 2.0.3 code. com.sun.faces.util.Util in 2.0.3 uses a ThreadLocal where the same class in 2.0.2 didn't. We cannot fix this issue, the message must have slipped unnoticed when 2.0.3 was released.

This log issue is preventing QA's automated testing system from being able to detect failures in the logs after tests are run, because there is always failures reported due to this issue.
