Problem conclusion
The JSF MyFaces 2.2 feature was updated to make the missing packages available on the thread context class loader so that a java.lang.ClassNotFoundException does not occur during deserialization of the session. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.8.
