Wildfly migration from 8.2 to 9 CR1

Question

I'm trying to migrate our project from Wildfly 8.2 to 9, and using version 9.0.0 CR1.

One of the problems I faced is with old EJB2 code. While in 8.2 everything works fine, in 9 I get

ERROR [org.jboss.as.ejb3.invocation] (MSC service thread 1-2) WFLYEJB0034: EJB Invocation failed on component MetadataInstanceFacade for method public abstract java.util.Collection com.mypackage.ejb.session.metadata.MetadataInstanceFacadeLocal.findByMetatypeAndUpperInstanceId2(java.lang.Integer,java.lang.Integer,java.lang.Boolean): javax.ejb.EJBException: java.lang.IllegalStateException: WFLYEE0067: Method does not exist public final java.util.Collection com.mypackage.ejb.session.metadata.InstanceFacadeBean.findByMetatypeAndUpperInstanceId2(java.lang.Integer,java.lang.Integer,java.lang.Boolean)

EJB2 interfaces and XML are generated by xdoclet.

Any ideas why it happens and how to fix this?

It was because of the final method modifier.

We face the same problem. Can you shed some light on why `final` is *evil* in this context? *Migrating form WildFly-8.1.0.Final to WildFly-9.0.1.Final here* – Robert Heine Sep 07 '15 at 08:44

"When generating a no-interface view proxy, the EJB container must create a subclass of the EJB class and override all public methods to provide proxying behavior." - so it can't do this, when method is final. – dds Sep 07 '15 at 08:48
Can you provide a source to this? I'm still confused that WF-8.x and WF-9.x seem to handle this THAT different. – Robert Heine Sep 07 '15 at 08:58

if you mean source in Wildfly, then I don't know, where this processing is. You you mean my source, it was just a method in EJB bean with public final method. You want me to show it? – dds Sep 07 '15 at 11:28
Sorry, I didn't mean the "sourcecode" in any form, but the source of the text in your quoutes. :) I thought you found that in some EJB spec or something. – Robert Heine Sep 07 '15 at 13:20
