[jboss-jira] [JBoss JIRA] (WFCORE-3512) EJBs can't inherit a JDK8 default method when default implementation is in a third interface

EJBs can't inherit a JDK8 default method when default implementation is in a third interface -------------------------------------------------------------------------------------------- Key: WFCORE-3512 URL: https://issues.jboss.org/browse/WFCORE-3512 Project: WildFly Core Issue Type: Bug Components: Server Reporter: Daniel Bildhauer Assignee: Stuart Douglas Attachments: ejb-in-ear.zip, wildfly-ejb-in-ear-ear.ear Given the following class/interface inheritance structure, the interface method doMagic could not be called from a remote view, even if there is a default implementation as given in the mixin interface. A local call works, but the remote call fails with a message like {code} org.jboss.invocation.CannotProceedException: INV000002: Invocation cannot proceed (end of interceptor chain has been hit) {code} Example code: {code} @Remote interface MyEJBInterface { void doMagic(); } interface MyEJBMixin extends MyEJBInterface { default void doMagic() { .... } } @Stateless class MyEJBBean extends MyEJBMixin { } {code} The problem is inside the fix for WFLY-4354 bug, which checks only for the default method implementation in the interface declaring the method the first time but not in other interfaces. A example is attached and I will submitt a pull request with a fix.
