Wildfly从8.2迁移到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?

这是由于final方法修饰符。
