I'm having a problem uploading files with the fileUpload component.  So far, I've tried disabling the CsrfGuard filter, the DataAccessAuthorityFilter, and the AuthorizationFailureFilter with no change in the error, other than a simplified stacktrace.  It worked fine with an earlier version of the code in Weblogic 10.3 with jsf 1.2, but ever since trying the code in Weblogic 12 with jsf 2.0, I'm getting the following error whenever an upload finishes:
