[jira] [Updated] (GROOVY-9253) Comparison between Enum and other objects should fail

["Xiaoguang Wang (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-9253?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xiaoguang Wang updated GROOVY-9253:
-----------------------------------
    Description: 
In Java, comparison between Enum and other objects always fail.

Groovy can follow the same behavior (at least in {{@CompileStatic}} mode) to keep consistency.

 
{code:java}
package com.company.test

import groovy.transform.CompileStatic

@CompileStatic
class TestEnumGroovy {
    enum E {
        a,b
    }
    static void main(String[] args) {
        E x = E.a
        String s = "A"

        System.out.print(x == s)  // it causes an error in Java. But Groovy doesn't see the error.
    }
}

{code}
