[jira] [Commented] (GROOVY-7778) CLONE - Enum constructor with value throws "unexpected token" error

["Paul King (JIRA)" <ji...@apache.org>]

Paul King commented on GROOVY-7778:
-----------------------------------

This is cloned from the original. This issue is to address whether we can tweak/finesse the grammar to remove the need for a semi-colon for the case of a dangling comma.

>          Components: Compiler
>    Affects Versions: 2.4.6

>            Priority: Minor

> First time submitter to this JIRA so let me know if I've specified anything incorrectly. I just upgraded from 2.4.4 to 2.4.6 and now declaring an enum constructor accepting a value as follows:
> {code:title=UsStates.groovy}
> enum UsState {
>   
>   ID('Idaho'),
>   IL('Illinois'),
>   IN('Indiana'),
>   
>   UsState( String value ) { this.value = value }
>   private final String value
>   
>   String toString() { return value }
> }
> println UsState.ID //Idaho
> {code}
> throws the following compile error:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> C:\svn_qa\jenkins_trunk\scripts\UsStates.groovy: 7: unexpected token: this @ line 7, column 29.
>      UsState( String value ) { this.value = value }
>                                ^
> 1 error
> {code}
> No such error occurred in 2.4.4, nor does it happen in 2.4.5. Here are a few contrasting things that do seem to work in 2.4.6:
> {code:title=UsStatesBoring.groovy}
> enum UsState {
>   
>   ID,
>   IL,
>   IN,
> }
> println UsState.ID //ID
> {code}
> {code:title=UsStatesNoEnum.groovy}
> class UsState {
>   
>   UsState( String value ) { this.value = value }
>   private final String value
>   
>   String toString() { return value }
> }
> final idaho = new UsState('Idaho')
> println idaho //Idaho
> {code}
> Though this seems higher priority than Minor, I can work around it by simply downgrading to 2.4.5. I wish there was a Medium priority.
