  - ### Method Detail

    - #### public static Object invokeGroovyObjectInvoker(MissingMethodException e, Object receiver, String name, Object[] args)

      GroovyObject.invokeMethod path as fallback. This method is called by the handle as exception handler in case the selected method causes a MissingMethodExecutionFailed, where we will just give through the exception, and a normal MissingMethodException where we call GroovyObject.invokeMethod if receiver class, the type transported by the exception and the name for the method stored in the exception and our current method name are equal. Should those conditions not apply we just rethrow the exception.

    - #### public static boolean isNull(Object o)

      Guard to check if the argument is null. This method is called by the handle to check if the provided argument is null.

    - #### public static boolean isSameMetaClass(MetaClass mc, Object receiver)

      called by handle

    - #### public static boolean sameClass(Class c, Object o)

      Guard to check if the provided Object has the same class as the provided Class. This method will return false if the Object is null.

    - #### public static Object setBeanProperties(MetaClass mc, Object bean, Map properties)

      This method is called by he handle to realize the bean constructor with property map.

    - #### public static Object unwrap(GroovyRuntimeException gre)

      Unwraps a GroovyRuntimeException. This method is called by the handle to unwrap internal exceptions of the runtime.

    - #### public static Object unwrap(Object o)

      Unwraps a Wrapper. This method is called by the handle to unwrap a Wrapper, which we use to force method selection.
