NPE in STSIssuingLoginModule when using JBWSTokenIssuingLoginModule in EAP 6.3.0.DR0. Method org.picketlink.identity.federation.core.wstrust.STSClientFactory.create(int, STSClientCreationCallBack) called from org.picketlink.trust.jbossws.jaas.JBWSTokenIssuingLoginModule.createWSTrustClient(STSClientConfig) returns null.

The bug has likely same cause as https://issues.jboss.org/browse/PLINK2-127

Stacktrace follows:
