> After fixing MYFACES-3530 I enabled Java2 Security in Websphere Application
> Server Version 8.0 and found the following issue related to using a custom
> Exception Handler to handle a ViewExpiredException.
> When we Navigate to a page from the customer Exception Handler in the
> application the following exception occurs:
> java.security.AccessControlException: Access denied

> I've attached Exception.txt showing the full stack trace for reference. The
> exception looks to come from:
> org.apache.myfaces.view.facelets.compiler.SAXCompiler.doCompileViewMetadata(SAXCompiler.java:712).
> I've attached a suggested patch that wraps the offending code in an
> AccessController.doPrivileged block. I had to make the following changes to
> completely fix the problem:
> 1) Make the ViewMetadataHandler and SAXParser local variables final so they
> can be used within the doPrivileged block.
> 2) I had to create a secondary InputStream object "finalInputStream which is
> just a copy of the local "is" InputStream but is marked final so it can also
> be used within the doPrivileged block.
> 3) I also added a nested try/catch block that will catch the
> PrivilegedActionException and catches the SAXException/IOException and keeps
> the behavior we had before ( throwing IOException, throwing new
> FaceletException for the SAXException ). I had to do this since the
> doPrivileged block wraps the exceptions from parser.parse in a
> PrivilegedActionException.
> 4) The new code is only used if System.getSecurityManager() != null so there
> should be no performance ramifications if security is not enabled.
> Please review and let me know if you are ok with my patch.
> Thanks!
