When I (attempt to) login to the explorer interface (it used to work, incidentally) I'm getting a NullPointerException in the DefaultLoginHandler authenticate method at line 41. The only thing there that would throw that is the identity service. I see where in the Spring config the identity service is created, and my db.properties looks correct. Is there anyway to confirm that the identity service is getting created correctly? There aren't any errors thrown during the application deployment, so I would guess that the datasource is created properly… not sure. Thoughts?
