After upgrading to 2.0.4, hystrix.stream does not work in Servlet environment

[alexsderkach]

I am using management.endpoints.web.base-path: ''.
After update from 2.0.3 to 2.0.4, I see a new class DispatcherServletPath.java which converts '' to /.
Then, ServletEndpointRegistrar.java comes into action with
String path = this.basePath + "/" + endpoint.getRootPath();

As a result, I see in logs:
o.s.b.a.e.w.ServletEndpointRegistrar : Registered '//hystrix.stream' to hystrix.stream-actuator-endpoint
And http://localhost:8081/hystrix.stream now returns 404.

Thanks for the report, you can use management.endpoints.web.base-path=/ for the time being. We may also tighten the rule regarding the format of such properties in a future release.

Actually, that comment above is wrong for the record so we really need a fix if you want to use the root.
