To allow the input to be mapped to the operation methods parameters, Java code implementing an endpoint should be compiled with -parameters, and Kotlin code implementing an endpoint should be compiled with -java-parameters. Because endpoints are technology agnostic, only simple types can be specified in the method signature. The path can be further customized by annotating one or more parameters of the operation method with @Selector.
