>                 Key: GROOVY-9253
>                 URL: https://issues.apache.org/jira/browse/GROOVY-9253
>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Xiaoguang Wang
>            Priority: Major
>
> In Java, comparison between Enum and other objects always triggers an error when compiling.
> 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}
