undeploy in tomcat prints warnings of thread local ContextStack
---------------------------------------------------------------
Key: CLK-706
URL: https://issues.apache.org/jira/browse/CLK-706
Project: Click
Issue Type: Bug
Components: core
Affects Versions: 2.2.0
Environment: Tomcat 6.0.26
Reporter: Finn Bock
Assignee: Finn Bock
Priority: Minor
With tomcat 6.0.26 on windows, starting the examples app, browse a page and
press crtl-C in the tomcat window causes tomcat to complain about a possible
memory leak:
SEVERE: A web application created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.threadlo...@bf015]) and a value of
type [org.apache.click.Context.ContextStack] (value [[]]) but failed to remove
it when the web application was stopped. To prevent a memory leak, the
ThreadLocal has been forcibly removed.
It is caused by Context.hasThreadLocalContext() which creates an empty
ContextStack if none existed before. Which is called by PerformanceFilter's
attempt to find the application version number.
