Reason:
JBoss uses wsdl4j-1.6.2.redhat-6.jar (Jboss version 6.2), which does not contain fix for the issue.
Path to jar in JBoss : \jboss-eap-6.2\modules\system\layers\base\javax\wsdl4j\api\main

[A NPE occurs when parsing a WSDL with the defined before the element. See stack trace below. The cause is in parseOperation - the line that sets 'op' to null if retrieved = true should be moved after the invocation of parseExtensibilityAttributes]
