[jira] [Created] (GROOVY-10811) Missing errors for improper enum declaration

Eric Milles created GROOVY-10811:
------------------------------------

             Summary: Missing errors for improper enum declaration
                 Key: GROOVY-10811
                 URL: https://issues.apache.org/jira/browse/GROOVY-10811
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles


Consider the following:
{code:groovy}
final enum E {
  FOO;
  E(int i) {
    super()
  }
}
{code}

* Explicit {{abstract}} or {{final}} modifier is supposed to be an error : "It is a compile-time error if an enum declaration has the modifier abstract or final." https://docs.oracle.com/javase/specs/jls/se11/html/jls-8.html#jls-8.9

* The enum constant declaration "FOO" does not supply an argument, which results in a runtime error.

* The special constructor call "super()" is not allowed by Java and results in a runtime error in Groovy.  "It is a compile-time error if a constructor declaration in an enum declaration contains a superclass constructor invocation statement (§8.8.7.1)."
