Application packaging custom login module used by JBoss EAP throwing exception trying to invoke CDI / EJBs in JBoss EAP 6

Issue

• I am packaging a custom login module in my application and the LoginModule invokes some CDI and EJB beans in the same application, but I am getting an error saying the Thread Context ClassLoader is is not associated with the deployment when my web request invokes the LoginModule:

DEBUG [org.jboss.security] (http-127.0.0.1:8080-1) PBOX000206: Login failure: javax.security.auth.login.LoginException: java.lang.IllegalStateException: JBAS016071: Singleton not set for org.jboss.as.security.plugins.ModuleClassLoaderLocator$CombinedClassLoader@9e81d4d. This means that you are trying to access a weld deployment with a Thread Context ClassLoader that is not associated with the deployment.
