Subject [jira] [Updated] (TAP5-2411) Tapestry webapp leaks a ThreadLocal
Date Fri, 31 Oct 2014 12:17:33 GMT

Jochen Kemnade updated TAP5-2411:
---------------------------------
    Description: 
When re-deploying a Tapestry webapp in a Tomcat container, I often see a warning like this:
{noformat}
21-Oct-2014 12:03:37.349 SEVERE [http-nio-9280-exec-14] org.apache.catalina.loader.WebappClassLoader.checkThreadLocalMapForLeaks
The web application [/webapp] created a ThreadLocal with key of type [org.apache.tapestry5.ioc.internal.services.PerthreadManagerImpl.
MapHolder] (value [org.apache.tapestry5.ioc.internal.services.PerthreadManagerImpl$MapHolder@55d6dc57])
and a value of type [java.util.HashMap] (value [{1=DEFINED, 2=DEFINED, 3=DEFINED, 4=DEFINED,
5=DEFINED, 6=DEFINED, 7=DEFINED, 8=DEFINED, 9=DEFINED, 10=DEFINED, 
11=DEFINED, 12=DEFINED, 13=DEFINED}]) but failed to remove it when the web application was
stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
{noformat}
I'm not yet sure where this comes from. It looks like a {{Map<Number, org.apache.tapestry5.ioc.services.Status>}}.
