Our configuration in web.xml is:
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/error.xhtml</location>
</error-page>
It worked with all versions of JBoss EAP until we updated to 7.2.6.
Now we are seeing our error page, but the page is shown without redirect - the URL remains the same (and not error.xhtml), javascript variables are not reseted (as with normal GET Request)
Maybe there is a way to configure error Page to be shown with GET?
