Spring Cloud - Zuul Server error

Question

Application.java

@Configuration
@ComponentScan
@EnableAutoConfiguration 
@EnableZuulProxy
public class ZuulServer {

     public static void main(String[] args) {
         SpringApplication.run(ZuulServer.class, args);
     }
 }

application.yml

  eureka:
    client:
      enabled: true
        serviceUrl:
           defaultZone: http://localhost:8761/v2/

  zuul:
    proxy:
       route:
         service1: /myservice1
         service2: /myservice2

Example calls:

http://localhost:8080/proxy/myservice1/users
http://localhost:8080/proxy/myservice2/auctionlots/today

Predecoration filter works during routing getting following error (using 1.0.0.M2) :

@vladsfl My sample app with your provided code works. That particular error comes from having an incompatible version (likely old) of rxjava. The version in my sample (and the version that works with hystrix) is com.netflix.rxjava:rxjava-core:jar:0.20.6. Can you provide your configuration? What version of rxjava do you have?
