Eric Milles resolved GROOVY-9306.
---------------------------------
Fix Version/s: 5.0.0-alpha-11
Resolution: Fixed
https://github.com/apache/groovy/commit/65506f4c5808e9625a93aee8c71523c2ced1739a
I went with the solution that most closely matches Java and eliminates
ambiguity. A constant-only {{enum}} can have a trailing comma. An {{enum}}
with constants and members requires no comma plus a newline or a semicolon for
separation.
> error for enum constant with comma followed by method

> Consider the following:
> {code:groovy}
> enum Orientation {
> LANDSCAPE, PORTRAIT,
>
> @Override
> String toString() {
> name().toLowerCase().capitalize()
> }
> }
> println Orientation.values()

> Parser error "unexpected token" for comma after PORTRAIT. Remove comma and no
> issue. Parsers support enum with trailing comma (no class members).
