Wildfly 9.0.1 VerifyError

[alex.austin]

We have an ear comprised of a few ejbs, wars, etc. that deploys and runs great on WIldfly 8.2.0. However when we try to deploy (Which appears to deploy just fine) and then access our application on the latest release of Wildfly 9 we are seeing this exception.

edit. As an FYI, the ear was compiled with and the system running our wildfly server are both using java "1.7.0_80"

Usually such kind of errors indicate a version mismatch. Did you include the netty-all-4.0.15.Final.jar to your EAR?

But Wildfly 9 uses netty-all-4.0.26.Final.jar which conflicts with the jar from wildfly 8.

[ctomc]

no, that shouldn't be a problem, as classloaders are scoped and netty never comes to user deployment classpath (unless asked for it in jboss-deployment-strucutre.xml)

what you have is clash between netty's javassit and the one you have in your deployment

netty uses 3.19.0-GA and you have 3.9. in your deployment.

and netty-all jar you are using is already shipping javassit as part of jar itself.

Hmm... now I have to dig deeper or look elsewhere. javassist is not specified in any of our poms and 3.9 is not in our maven repo just 3.18.1-GA

[alex.austin]

So the 3.9 is a dependency of Hibernate 3.5.2, however wouldn't a javassist issue have popped up in previous versions of jboss/wildfly such as Jboss 7 or Wildfly 8.2 since they use more recent versions of javassist?

I would be surprised if you couldn't update WildFly to use a later Javassist version.  We have been talking about doing that for a while and just need to coordinate it.  Perhaps you could try 3.20.0-GA and let us know how it goes (success or failure).
