    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. java.lang.IllegalStateException: getOutputStream() has already been called for this response at org.apache.catalina.connector.Response.getWriter(Response.java:599) at org.apache.catalina.connector.ResponseFacade.getWriter(ResponseFacade.java:195) at org.apache.jasper.runtime.JspWriterImpl.initOut(JspWriterImpl.java:124) at org.apache.jasper.runtime.JspWriterImpl.flushBuffer(JspWriterImpl.java:117) at org.apache.jasper.runtime.PageContextImpl.release(PageContextImpl.java:191) at org.apache.jasper.runtime.JspFactoryImpl.internalReleasePageContext(JspFactoryImpl.java:115) at org.apache.jasper.runtime.JspFactoryImpl.releasePageContext(JspFactoryImpl.java:75) at org.apache.jsp.errors._404_jsp._jspService(_404_jsp.java:67) 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> <filter-name>MyFacesExtensionsFilter</filter-name> <filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class> <init-param> <description>Set the size limit for uploaded files.
