Jsf. Suppress stderr log.

[zgood]

Hello! I have a problem with jsf logs in gatein 3.0.0GA.

I have incorrect EL expression in jsf code, or EL expression which throws an Exception. After rendering jsf in logs i see javax.portlet.PortletException: Error process faces request stacktrace twice: in ERROR [javax_portlet_faces_GenericFacesPortlet] and in ERROR [STDERR]:

{noformat}15:47:12,917 ERROR [javax_portlet_faces_GenericFacesPortlet] The portlet threw an exception
javax.portlet.PortletException: Error process faces request
        at javax.portlet.faces.GenericFacesPortlet.doFacesDispatch(GenericFacesPortlet.java:600)
        at javax.portlet.faces.GenericFacesPortlet.doView(GenericFacesPortlet.java:486)
...
15:47:12,953 ERROR [STDERR] javax.portlet.PortletException: Error process faces request

15:47:12,953 ERROR [STDERR]     at javax.portlet.faces.GenericFacesPortlet.doView(GenericFacesPortlet.java:486)

Is there way to suppress stderr jsf logs?
