Description

If I have the ExtensionsFilter configured in my web.xml it throws an error whenever a page is not found saying that the response is already committed instead of just displaying the 404 error page that I have created.

If I comment out the ExtensionsFilter it works fine and displays the 404 splash page from my application as it should. Here is the snippet from my web.xml:

<filter>
