Description

I have a class with static utility methods. I have done 'mixin' this class into another class using @Mixin annotation and then while calling static overloaded method I give runtime error.

Utility class:

class UtilClass {
    public void callClassOverloadedMethod(String s) {
        System.out.println("callClassOverloadedMethod(String)");
    }
    public void callClassOverloadedMethod(String s, Object o) {
        System.out.println("callClassOverloadedMethod(String, Object)");
    }
    public static void callStaticOverloadedMethod(String s) {
        System.out.println("callStaticOverloadedMethod(String)");
    }
    public static void callStaticOverloadedMethod(String s, Object o) {
        System.out.println("callStaticOverloadedMethod(String, Object)");
    }
}

Main class:

@Mixin(UtilClass)
class MainClass {
    public static void main(String []s) {
        MainClass mc = new MainClass()
        mc.callMixinMethods()
    }

    void callMixinMethods() {
        callClassOverloadedMethod("")
        callStaticOverloadedMethod("")
    }
}

Run command:

groovy -cp . MainClass

Error:

Caught: org.codehaus.groovy.runtime.metaclass.MethodSelectionException: Could not find which method callStaticOverloadedMethod() to invoke from this list:
  public static void UtilClass#callStaticOverloadedMethod(java.lang.String)
  public static void UtilClass#callStaticOverloadedMethod(java.lang.String, java.lang.Object)
        at MainClass.callMixinMethod(MainClass.groovy:20)
        at MainClass.main(MainClass.groovy:12)

Please fix this trouble, it prevent me to write code and tests.
