[jira] [Commented] (GROOVY-11256) Fail to identify direct call of abstract method

["Eric Milles (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-11256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17799596#comment-17799596 ] 

Eric Milles commented on GROOVY-11256:
--------------------------------------

Usage of "Type.super.method()" was recently opened up for interfaces with static and private methods.  Groovy 3 tells me "The usage of 'Type.this' and 'Type.super' is only allowed in nested/inner classes."
