You can use dp4j command-line to answer your question:

    $ javac -cp ../dp4j-1.2-SNAPSHOT-jar-with-dependencies.jar -All -Averbose=true MyClass.java
MyClass.java:7: Note: 
public class MyClass {

public MyClass() {
    super();
}

public void myMethod(Object... args) {
    System.out.println("this is myMethod");
}

@com.dp4j.Reflect()
public void invokeMyMethod() throws java.lang.ClassNotFoundException, java.lang.NoSuchFieldException, java.lang.IllegalAccessException, java.lang.NoSuchMethodException, java.lang.reflect.InvocationTargetException, java.lang.IllegalArgumentException {
    final java.lang.reflect.Method myMethodWithArrayMethod = Class.forName("MyClass").getDeclaredMethod("myMethod", .java.lang.Object[].class);
    myMethodWithArrayMethod.setAccessible(true);
    myMethodWithArrayMethod.invoke(this, new .java.lang.Object[1][]{new .java.lang.Object[2][]{"hi", "there"}});
}

public static void main(String... args) throws Exception {
    new MyClass().invokeMyMethod();
}
}
public void invokeMyMethod() {
            ^

$ java MyClass
this is myMethod
