EclipseLink 2.6.1 (final) throws the following exception upon deploying a Java EE application on GlassFish Server 4.1. This had not been happening prior to upgrading from 2.6.0.

Although it is a java.lang.NullPointerException, the LOG level is Warning.
org.eclipse.persistence.sessions.factories.SessionManager#init() is defined as follows (though grepcode shows RC1).
74 private static void init() {
75 String platformClass = ServerPlatformUtils.detectServerPlatform(null);
76 try {
77 detectedPlatform = ServerPlatformUtils.createServerPlatform(null, platformClass, SessionManager.class.getClassLoader());
78 } catch (NullPointerException npe) {
79 //some platforms may not be handling 'null' session well,
80 //so be defensive here and only log throwable here
81 detectedPlatform = null;
82 LOG.logThrowable(SessionLog.WARNING, AbstractSessionLog.CONNECTION, npe);
83 }
84 supportPartitions = detectedPlatform != null && detectedPlatform.usesPartitions();
85 if (supportPartitions) {
86 managers = new ConcurrentHashMap<String, SessionManager>(4, 0.9f, 1);
87 SessionManager sm = initializeManager();
88 manager = sm;
89 managers.put(sm.context, sm);
90 } else {
91 manager = initializeManager();
92 }
93 }
Where createServerPlatform(DatabaseSession session, String platformClass, ClassLoader loader) throws a java.lang.NullPointerException, if platformClass is null.
97 public static ServerPlatform createServerPlatform(DatabaseSession session, String platformClass, ClassLoader loader) {
98 if (platformClass == null) {
99 throw new NullPointerException();
100 }
//...
}
It appears to be normal according to the code. Is it?
