Description
Under certain conditions I am seeing the following exception:
Caused by: java.io.NotSerializableException: org.icefaces.application.PushRenderer$2
To replicate I:
1) Deploy and run the ACE Showcase
2) Choose the ace:progressBar > Push example and run the progress bar
3) Shut down Tomcat and restart it (which should serialize/deserialize the current session)
It seems that the LongTaskManager class is a window-scoped bean used in the noted example and that it keeps a reference to a PortableRenderer - an anonymous inner class of PushRenderer - and the inner class is not Serializable. This is by design.
Simply marking the "private PortableRenderer renderer" instance as transient has side effects that break the proper operation of the progress bar.

Acquire PortableRenderer just before progress bar thread is started. This way there's no need to handle PortableRenderer's serialization/deserialization.

It's easier to reproduce by running with MyFaces and changing the scope of LongTaskManager to ViewScoped (from Window). That way it attempts to serialize on each request.
