            Description

            Server warning when removing showcase from Tomcat 8. I was able to produce these warnings by testing only the native demos such as camera, camcorder, fetch-contact etc. then removing the .war file from the server. This appears different from the usual server warnings occasionally seen when removing showcase from the server.

              The fix for the first warning was to replace SynchronizationMonitorObject instances with String object instances to avoid NoClassDefFoundError errors when application was removed from the file system and the web context was not yet fully disposed.

              The fix for the second warning was to capture the NoClassDefFoundError error in QueueConsumerTask.run that occurs when application is removed from file system and QueueConsumerTask is not disposed yet by the servlet's container context disposed event.

              There's still a warning left that is triggered by Mojarra:

              This warning was already covered by ICE-10377 .

              Tested with ICEfaces 4 trunk r47049. Tomcat 8.0.15, Windows 7, ipad ios 9.1, Android 6.0.1 phone using Mobile Showcase from the showcase.war file. The warnings as written in the description of this JIRA are still appearing. I was able to reproduce them by using a cleared cache ChromeSafari browser. I interacted with 4 demos (camcorder, camera, cloud push and fetch contact) then I removed the .war file from the server. The error message also appeared when using the sms QA test application found at:

              I still cannot reproduce the severe warnings described above. For testing I used both showcase and sms applications. The tests were run on OSX 10.10 and Windows 8 with Tomcat 8.0.23.

              Can you please specify the exact server side environment you are using to run the tests?

              This turns out to be a Tomcat issue. Tomcat version 8.0.17 will provide a different ServletContext instance to ServletContextListener.contextInitialized than to ServletContextListener.contexDestroyed. Mojarra keeps track of the created servlet context instances and when one of the context is destroyed will verify if it was created in the first place. If not found Mojarra will skip the context cleanup process, that includes any thread locals, thread pools or disposing application scoped beans.
              Somewhere in between Tomcat version 8.0.17 and version 8.0.23 the issue was fixed because the issue does not occur in 8.0.23 or later.

              Really fixing this issue is out of our reach.
