Hey guys,
we developed an play application (Currently 2.5.6, startimg with play 2.4) and it worked like a charm.
Some days ago I added a configuration line to application.conf:
On server start play told me that this config is deprecated and it should change to a new one:
Fine. So I remove the old config and added the new one:
and start the server with
the server could not start due to a NPE while accessing the database (db() in com.avaje.ebean.Model.java is null) in the Initializer (Custom class according to Play docs to create some database entries on startup if database is empty. Called via @Inject from the Filters class).
Strange fact part I:
If I remove the play.http.session.cookieName the error still occurs, only reAdd the session.cookieName line helps the server to startup. I rolled back the commits.
Strange fact part II:
Starting the server in development mode (activaor ~run) doesn't result in an NPE
I checked the logfiles and it seems that, if the play.http.session.cookieName is added to the application.conf the Initializer is called 3 times instead of one-time! Below are the 2 log files. First without the play.htttp.session.cookieName and the second with. The lines
are logged from the initilaizer. If the Initializer has been processed completetly the line
will be logged. So we see the first two lines 3 times, the last line only one-time.
I have really no idea what is going on here, I am appreciate for any suggests or help.
With best regards

I'm pretty unfamiliar with ebean, but is the db() a static method that requires some initialization to work? What guarantees that this initialization has happened?
It's possible this isn't directly because of the configuration change, but rather a slight difference in the timing of initialization.

Mhm, Google deleted my post - again:
Hey Greg,

I think this should be happen during some "dependency initialization" phase. db() returns an Ebean Server which will be created inside a synchronized block. Maybe Guice is triggered too early so it will instanciate its Singleton (The CustomInitializer) three times instead of one-time, and as far as I understand the 2.5. docs the Initializer can be used to fill the database with seed data.
It's possible this isn't directly because of the configuration change, but rather a slight difference in the timing of initialization.
Yes - I think is just a symptom. In fact something in the Lifecycle has been changed after adding the config. And there has to be a difference between development mode (~run) and release mode (dist).
Thanks and best regards

I checked an very early version of our software and I can see a similiar problem.
We included liquibase, which will migrate the database on startup. It seems, that if there is no database and liquibase has to create the new one the lifecycle of play is too fast, so the Initializer is called too often. If there are complex tasks for play (like actor module, cookie name etc.) liquibase has enough time to migrate and let the jdbc opens a connection.
Otherwise the first two calls to the CustomInitializer results in an Timeout (from the synchronized block) and then in an Exception.
So it seems to me, that "something" in the lifecycle with Play, Guice, Liquibase is broken.
Regards
