[Ugo Bourdon]

I try to upgrade my reactive mongo driver version to 0.11.6 with an 2.3.8 play apps.

I succeed to compile my code, and my mongo repository unit test works fine.

But when i start the app & request some route that request mongo db, I have this fatal error that crashing my app :

Uncaught error from thread [play-akka.actor.default-dispatcher-17] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for ActorSystem[play]

Any idea of what happen ?

Thx for your response.

Play 2.3.8 is using Netty 3.9.3, ReactiveMongo 0.11.6 is using Netty 3.10.4 Final, so you should have a linkage error.
Either you upgrade Play, or you downgrade ReactiveMongo.

As for Play 2.3.x, the Play-ReactiveMongo is only tested with 2.3.9.

I upgrade my play version to 2.3.10 but I have the same issue.
Then I downgrade to play 2.3.9 and it was the same.
So reactive mongo 0.11.x don't work with play 2.3.x ?

[Cédric Chantepie]

Please check you don't have multiple versions of Netty. The play module is tested successfully with 2.3.9.

[Ugo Bourdon]

It's tested with running the play server ?
Because my unit test with reactive mongo works well.
Just when I run the play server, it crash when I perform request using mongo request.

[Ugo Bourdon]

Do you know how I do that ?

[Ugo Bourdon]

So I think I find a lib which use another hided version of netty.
But no I have the same issue but with another stask trace

[ERROR] [08/19/2015 15:14:37.146] [play-akka.actor.default-dispatcher-2] [ActorSystem(play)] Uncaught error from thread [play-akka.actor.default-dispatcher-2] shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled
java.lang.NoClassDefFoundError: Could not initialize class application.authentication.binding.json.UserJsonFmt$

It can't load my JsonFormat class. Any Idea of that ?

[Cédric Chantepie]

Do you have filtered the dependency also using Netty? Is this dependency defining the JSON class?

[Ugo Bourdon]

Plz look that : https://github.com/ubourdon/testReactiveMongo/

[Cédric Chantepie]

Try to update your build.sbt as following.

libraryDependencies ~= { _ map {
  case m => m.exclude("io.netty", "netty")
} }

libraryDependencies += "io.netty" % "netty" % "3.9.9.Final" // From Play 2.3.10 dependencies

[Ugo Bourdon]

Thx. It seems working well.
