--------------------------------------------------------------

The parser currently sees "super \{ ... \}" as a method call expression (expression switch selects {{org.codehaus.groovy.antlr.AntlrParserPlugin#methodCallExpression}}).  A "this(...)" or "super(...)" call is recognized separately by {{org.codehaus.groovy.antlr.AntlrParserPlugin.specialConstructorCallExpression}}.

>                 URL: https://issues.apache.org/jira/browse/GROOVY-9363
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.5.8
>            Reporter: Björn Kautler
>            Priority: Major
>
> Given this script:
> {code:groovy}
> import java.util.function.Supplier
> class Foo {
>     Foo(Supplier<?> supplier) {
>     }
> }
> class Bar extends Foo {
>     Bar() {
>         super { null }
>     }
> }
> new Bar()
> {code}
> I'd expect everything to be ok, but the compiler complains that "Constructor call must be the first statement in a constructor".
> Using {{super(\{ null \})}} instead works fine.
