/*
 * Unit test for https://glassfish.dev.java.net/issues/show_bug.cgi?id=815
 * ("Impossible for JSP error page to set response encoding when invoked
 * from another JSP"):
 *
 * Test configures error pages for 403 response code and Throwable, see
 * web.xml.
 *
 * Test accesses 403.jsp, which sets the response code to 403 and therefore
 * causes a forward to the error403.jsp error page, which sets the response
 * content type to text/xml;charset=Shift_JIS.
 * 
 * Test then accesses throwable.jsp, which throws a Throwable and therefore
 * causes a forward to the errorThrowable.jsp error page, which sets the
 * response content type to text/xml;charset=Shift_JIS.
 *
 * Test enforces that both responses carry this content type, and reports
 * an error otherwise.
