      Description

      Tried this example and got cast exception converting Map to Integer. Should the print statement at the end use the generated map constructor as expected? (Note: I am compiling with indy variant; tried to use web console to try vanilla MOP...)

      import groovy.transform.*
      import groovy.transform.options.*
      
      @ToString(includeNames=true)
      class Color {
        final Integer r, g, b
      
        @NamedVariant @VisibilityOptions(Visibility.PUBLIC)
        private Color(Integer r, Integer g, Integer b) {
          this.r = r
          this.g = g
          this.b = b
        }
      
        public static final Color BLACK = new Color(0, 0, 0)
      }
      
      print(new Color(g:12, b:42, r:12)) // gives org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '{}' with class 'java.util.LinkedHashMap' to class 'java.lang.Integer'
