Subject [jira] [Commented] (POLYGENE-251) Support Java 8 default methods on interfaces
Date Mon, 15 May 2017 11:06:04 GMT

    [ https://issues.apache.org/jira/browse/POLYGENE-251?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16010327#comment-16010327
] 

Niclas Hedhman commented on POLYGENE-251:
-----------------------------------------


However, it seems that if there is no Concern/SideEffect/Constraint, then it seems that the
default method is called directly. Ah. So does that mean if there are only InvocationHandlers
as Concerns/SideEffects, that those will not be invoked?
