Spring boot microservice (jdk11) threw hystrix.stream-actuator-endpoint exception

Question

After spring boot service migration to 2.1.3.RELEASE and jdk11, hystrix stream actuator-related exceptions occur.

The exception is ERROR org.apache.catalina.core.ContainerBase.[Tomcat-1].[localhost].[/].[hystrix.stream-actuator-endpoint] - Servlet.service() for servlet [hystrix.stream-actuator-endpoint] in context with path [] threw exception[]

---

Spring boot version: 2.1.3.RELEASE

Java version: 11

All actuator endpoints are exposed: management.endpoints.web.exposure.include=*

Also, hystrix.stream endpoint is actually enabled and gives a stream. Nevertheless, exceptions still occur in logs

Answer 1

Running the minimal configuration I'm unable to reproduce the problem, I tried switching version from 2.1.3-RELEASE to 2.2.2-RELEASE too; no problems. So I think you should give more details here. Where is executing your application? Embedded tomcat, external tomcat, docker? Try to give more details please.

In case you are using Eureka server:
Official docs says

The JAXB modules which the Eureka server depends upon were removed in JDK 11. If you intend to use JDK 11 when running a Eureka server you must include these dependencies in your POM or Gradle file.
