[jboss-user] [Security & JAAS/JBoss] - NullPointerException in getCallerPrincipal()

[johanmicoud]

I have upgraded to JBoss 5.0.0 CR1. 
Client side, my authentification uses JndiLoginContextFactory with

env.put(Context.SECURITY_PRINCIPAL,"user");
env.put(Context.SECURITY_CREDENTIALS, "password");

Server side, every call to getCallerPrincipal() raises a NullPointerException in EJBContextHelper (!!).

Here is the stack trace :
