The parameters passed to endpoint operation methods are, if necessary, automatically
converted to the required type. Before calling an operation method, the input received via
JMX or an HTTP request is converted to the required types using an instance of
`ApplicationConversionService`.
`ApplicationConversionService` as well as any `Converter` or `GenericConverter` beans
qualified with `@EndpointConverter`.
