Check the above jar files against the available jars in the classes and classes_alt directories for any extra jars that may be causing the conflict/issue. Possible files to look out for are listed below (more will be added when found):

activation.jar
activation-1.1.jar
mail-1.4.jar 

If found, try moving the jar file out of the classes or classes_alt directory, restart all Applications Manager processes, and check to see if the issue is resolved.
