Description

If a exception occurs in render response phase (see MYFACES-3191), exception and its stacktrace is outputed 2x in log:
1) from org.apache.myfaces.view.facelets.FaceletViewDeclarationLanguage.handleRenderException
2) from ExceptionHandlerImpl/ErrorPagewriter

The first one is unwanted, because all exceptions should be handled with exception handling mechanism. Remove that logging or change its level to FINE.
