[jira] [Commented] (GROOVY-9987) MissingMethodException when a base class calls a private static method inside a closure

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

    [ https://issues.apache.org/jira/browse/GROOVY-9987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17527499#comment-17527499 ] 

Eric Milles commented on GROOVY-9987:
-------------------------------------

This kind of construction should be possible.  You can work around the problem by making the method protected or package-private or marking the class with @CompileStatic.
