Issue

• We use httpunit to run test cases against JBoss. All test cases worked against EAP 5, but with EAP 6, the test client fails if a test involves a response with a custom error response code (some untypical HTTP response 400 or greater):

Server returned HTTP response code: 453 for URL: http://localhost:8080/helloworld/453.jsp
java.io.IOException: Server returned HTTP response code: 453 for URL: http://localhost:8080/helloworld/453.jsp
