HttpTraceFilter bean missing when using Eureka Server

[marcingrzejszczak]

For latest snapshots, when running the contract samples I started getting

[ERROR] org.springframework.cloud.contract.stubrunner.spring.cloud.eureka.StubRunnerSpringCloudEurekaAutoConfigurationSpec  Time elapsed: 4.376 s  <<< ERROR!
org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat

in order to work around this I needed to add a filter with that name:

@Configuration
    @EnableAutoConfiguration
    @EnableEurekaServer
    static class EurekaServer {

        @Bean
        Filter httpTraceFilter() {
            return new Filter() {
                @Override
                void init(FilterConfig filterConfig) throws ServletException {

                }

                @Override
                void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
                    filterChain.doFilter(servletRequest, servletResponse)
                }

                @Override
                void destroy() {

                }
            }
        }


    }

I'm having same problem, my workaround:

@ConditionalOnMissingBean
@Bean
public HttpTraceRepository httpTraceRepository() {
  return new InMemoryHttpTraceRepository();
}

Possible caused by: spring-projects/spring-boot@de128fe / spring-projects/spring-boot#15039

Should be easy to fix - just add a @Conditional to that bean definition that is failing.
