Currently, the guide https://spring.io/guides/gs/gateway/#_writing_tests suggest to use "WireMock from Spring Cloud Contract in order stand up a server".
Unit tests of the people using this library to make gateways would be more performant, easier to write and more stable if they didn't make real tcp connections to do http reques

Please check the reproducible example here: https://github.com/michaelr524/reactor-netty-ssl-leak

mvn clean package

Per the reactive-streams spec items 1.6 and 3.7 combined, once a stream is complete, any cancel signal should be ignored.

This is not the case with reactor-grpc, which can have drastic effects as we saw in the following setup

We're using cf-java-client in a multi-threaded application. Are DefaultConnectionContext etc. thread-safe? This is not documented right now, and they make heavy use of threading internally (with thread pools etc.), which makes me wonder at what kind of level I can reuse objects between threads (can I reuse clients? connection contexts? none of the above?)

Here is the doc of CacheFlux with the map endpoints:

      String key = "myCategory";
      LoadingCache<String, Object> graphs = Caffeine
          .newBuilder()
          .maximumSize(10_000)
          .expireAfterWrite(5, TimeUnit.MINUTES)
          .refreshAfterWrite(1, TimeUnit.MINUTES)
          .build(key -> createExpensiveGraph(key));
  
      Flux<Integer> cachedMyCategory =

feign.reactor.version=1.0.30
Final request path: ReactiveFeignClient.path + "/" + GetMapping.value
If GetMapping.value is default "/" is added anyway.
The behavior is different from FeignClient

Example:

@GetMapping(produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
Result get(@RequestParam(value = "param") );

@ReactiveFeignClient(
path = "/my/path",
)

Expecte

DtCraft has a built-in reactor for event-driven programming. We will add a chapter discussing the basics in our cookbook.

http://docs.spring.io/spring-framework/docs/5.0.0.BUILD-SNAPSHOT/spring-framework-reference/html/web-reactive.html#web-reactive-websocket-support

WebFlux includes reactive WebSocket client and server support. Both client and server are supported on the Java WebSocket API (JSR-356), Jetty, Undertow, Reactor Netty, and RxNetty.

On the server side, declare a WebSocketHandlerAdapter and then sim
