PI71585: NullPointerException when null password is passed into WSCallBackHandlerFactory

Fixes are available

APAR status

Closed as program error.

Error description

we are in the process of migrating our application from
WAS-ND
7.0.0.41 to Liberty 16.0.0.2.  We have encountered a problem
with some identity assertion code that our MDBs use.  It
looks
like the Liberty APIs do not allow a null password to be
passed
to the
WSCallbackHandlerFactory.getInstance().getCallbackHandler()
method.  We implemented this code with the help of IBM
consultants and with reference to this article:

http://www.ibm.com/developerworks/websphere/techjournal/1303
_lan
sche/1303_lansc he.html

Here is our code in question:
CallbackHandler handler =
WSCallbackHandlerFactory.getInstance().
getCallbackHandler(xxx.getSystemId(), (String) null);

When this method is invoked (in the onMessage method of our
MDBs) we get a NullPointerException coming from IBM's code.
What is the proper way to assert a system identity to
Liberty
with no password required?

Here is the entire stack trace:
java.lang.NullPointerException
at com.ibm.ws.security.jaas.common.internal.callback.
WSCallbackHandlerFactoryImpl.createBasicAuthenticationData
(WSCallbackHandlerFactoryImpl.java:177)
at com.ibm.ws.security.jaas.common.internal.callback.
WSCallbackHandlerFactoryImpl.getCallbackHandler
(WSCallbackHandlerFactoryImpl.java:36)
