        java.lang.Object intercept​(java.lang.Object obj,
                                   java.lang.reflect.Method method,
                                   java.lang.Object[] args,
                                   MethodProxy proxy)
                            throws java.lang.Throwable
        All generated proxied methods call this method instead of the original method. The original method may either be invoked by normal reflection using the Method object, or by using the MethodProxy (faster).
        Parameters:
        obj - "this", the enhanced object
        method - intercepted Method
        args - argument array; primitive types are wrapped
        proxy - used to invoke super (non-intercepted method); may be called as many times as needed
        Returns:
        any value compatible with the signature of the proxied method. Method returning void will ignore this value.
        Throws:
        java.lang.Throwable - any exception may be thrown; if so, super method will not be invoked
