Subject [jira] [Commented] (GROOVY-8760) can't instantiate a class that inherits from base class marked with @MapConstructor
Date Tue, 21 Aug 2018 10:27:00 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-8760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16587264#comment-16587264
] 

Paul King commented on GROOVY-8760:
-----------------------------------

Using @MapConstructor(noArg=true) on A or @InheritConstructors on class B works for me.
