  /**
   * Invokes the underlying method represented by this {@code Method} object, on the specified
   * object with the specified parameters. Individual parameters are automatically unwrapped to
   * match primitive formal parameters, and both primitive and reference parameters are subject to
   * method invocation conversions as necessary.
   *
   * <p>If the underlying method is static, then the specified {@code obj} argument is ignored. It
   * may be null.
   *
   * <p>If the number of formal parameters required by the underlying method is 0, the supplied
   * {@code args} array may be of length 0 or null.
   *
   * <p>If the underlying method is an instance method, it is invoked using dynamic method lookup as
   * documented in The Java Language Specification, Second Edition, section 15.12.4.4; in
   * particular, overriding based on the runtime type of the target object will occur.
   *
   * <p>If the underlying method is static, the class that declared the method is initialized if it
   * has not already been initialized.
   *
   * <p>If the method completes normally, the value it returns is returned to the caller of invoke;
   * if the value has a primitive type, it is first appropriately wrapped in an object. However, if
   * the value has the type of an array of a primitive type, the elements of the array are
   * <i>not</i> wrapped in objects; in other words, an array of primitive type is returned. If the
   * underlying method return type is void, the invocation returns null.
   *
   * @param obj the object the underlying method is invoked from
   * @param args the arguments used for the method call
   * @return the result of dispatching the method represented by this object on {@code obj} with
   *     parameters {@code args}
   * @exception IllegalAccessException if this {@code Method} object is enforcing Java language
   *     access control and the underlying method is inaccessible.
   * @exception IllegalArgumentException if the method is an instance method and the specified
   *     object argument is not an instance of the class or interface declaring the underlying
   *     method (or of a subclass or implementor thereof); if the number of actual and formal
   *     parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after
   *     possible unwrapping, a parameter value cannot be converted to the corresponding formal
   *     parameter type by a method invocation conversion.
   * @exception InvocationTargetException if the underlying method throws an exception.
   * @exception NullPointerException if the specified object is null and the method is an instance
   *     method.
   * @exception ExceptionInInitializerError if the initialization provoked by this method fails.
