Description

The following code works fine from Java but fails in Groovy:

public abstract class FooMain {
    private FooMain() {}
    public abstract String bar();
    public static FooMain factory() {
      return new FooMain() {
        public String bar() { return "xxx"; }
      };
    }
    public static void main(String[] args) {
        System.out.println(factory().bar());
    }
}
// => java.lang.IllegalAccessError: tried to access method FooMain.<init>()V from class FooMain$1
