[jira] [Closed] (GROOVY-9724) Elvis operator covert double to null in addiction

["Scott.Wu (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Scott.Wu closed GROOVY-9724.
----------------------------
    Resolution: Invalid

This "issue" is related to println shorthand.  Meanwhile, Elvis has much lower priority than "+" operator, so we need to apply bracket for the elvis expression.

 

Current logic is correct and the issue is not valid now.
