The server exits on start with an exception, when logging for com.goldencode.p2j.persist.Persistence (or parent package) is enabled on level CONFIG or lower. The error log is as follows:

Caused by: java.lang.NullPointerException
    at com.goldencode.p2j.persist.orm.SessionFactory$SessionCloseThread.register(SessionFactory.java:315)
    at com.goldencode.p2j.persist.orm.SessionFactory$SessionCloseThread.access$000(SessionFactory.java:239)

    at com.goldencode.p2j.persist.Persistence.createLockManager(Persistence.java:3593)
    at com.goldencode.p2j.persist.Persistence.initializeTenant(Persistence.java:3520)

The cause is that SessionCloseThread.register is called before SessionCloseThread.initialize by trying to log LOG.config(message("lock manager initialized [" + className + "]"));. This happens during Persistence.initialize(), because DatabaseManager.initialize() (instantiating Persistence.context) is called before SessionFactory.SessionCloseThread.initialize();.

Galia,
for some reason, the stack trace line number are not matching with my revision (either because of my mine changes or - less probable - yours).

Please check whether the Persistence.message() method looks like this:

   public String message(String message)
   {
      Context[] ctxs = contexts.get(false);
      Context ctx = (ctxs == null) ? null : ctxs[PRIVATE_IDX];  
      return "[" + Utils.describeContext() + "-->" +
             (ctx != null ? ctx.tenant.database : defaultTenant.database) +
             "] " + message;
   }

The important thing here is contexts.get(false). It prohibits the creation of a new context since one is not needed at this time.

You may need to rebase your branch.

The branch I test on is not updated indeed. The issue seems to be fixed on trunk. The task can be closed.
