              This issue seems to have been resolved by the fixes for ICE-10408 (rev. #43576).

              There's still this SEVERE message shown when running with Mojarra:

              Dec 2, 2014 11:23:33 PM org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
SEVERE: The web application [/showcase] created a ThreadLocal with key of type [com.sun.faces.application.ApplicationAssociate$1] (value [com.sun.faces.application.ApplicationAssociate$1@2ed7c530]) and a value of type [com.sun.faces.application.ApplicationAssociate] (value [com.sun.faces.application.ApplicationAssociate@57d2ea56]) 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.

              After debugging it turns out that the ThreadLocal is created by Mojarra in com.sun.faces.application.ApplicationAssociate.

              Modified ICEpush bridge to shutdown blocking connection on beforeUnload. This aborts the blocking connection and unblocks the corresponding thread on the server.

              Tested with ICEfaces 4 trunk r43821.
              After using the cloud push demo (simple push, priority push), then undeploying showcase, the following server errors are seen:
