Description

The Groovy parser does not allow a trailing comma in an enum definition:

enum Foo {
X, Y, Z,
}

According to the Java language specification (V. 3):

EnumDeclaration: ClassModifiers_opt enum Identifier Interfaces_opt EnumBody
EnumBody: { EnumConstants_opt ,_opt EnumBodyDeclarations_opt }

Note the ",_opt" in the EnumBody.
