/*
 * Unit test for Bugzilla 13924 ("error-page directive does not always
 * work correctly").
 *
 * According to SRV.9.9.2:
 *
 *  If no error-page declaration containing an exception-type
 *  fits using the class-hierarchy match, and the exception thrown is a
 *  ServletException or subclass thereof, the container extracts the
 *  wrapped exception, as defined by the ServletException.getRootCause
 *  method. A second pass is made over the error page declarations, again
 *  attempting to match against the error page declarations, but using the
 *  wrapped exception instead.
 *
 * We used to match only the wrapped exception against any error-page
 * decls, but never the wrapping ServletException.
