Spring-cloud-netflix: EurekaClient without Jersey throws unrecognized field exception with Finchley RC1

Created on 17 May 2018 · 9Comments · Source: spring-cloud/spring-cloud-netflix

This relates to some undesirable behaviour originally reported in #2756.

A simple Eureka client application built with the Jersey client modules excluded from its org.springframework.cloud:spring-cloud-dependencies:Finchley.RC1 throws an error every time it attempts to refresh its local cache of registry information. The root cause of the problem appears to be a JSON parsing error relating to an unrecognised field called "overriddenStatus" in the returned instance information. A small snippet of the stack trace is shown below:

2018-05-17 11:55:49.605  WARN 5170 --- [freshExecutor-0] c.n.d.s.t.d.RetryableEurekaHttpClient    : Request execution failed with message: Error while extracting response for type [class org.springframework.cloud.netflix.eureka.http.EurekaApplications] and content type [application/json]; nested exception is org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unrecognized field "overriddenStatus" (class com.netflix.appinfo.InstanceInfo), not marked as ignorable; nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "overriddenStatus" (class com.netflix.appinfo.InstanceInfo), not marked as ignorable (28 known properties: "port", "healthCheckUrl", "appGroupName", "sid", "instanceId", "countryId", "hostName", "isCoordinatingDiscoveryServer", "vipAddress", "securePort", "secureHealthCheckUrl", "overridden_status", "asgName", "app", "overriddenstatus", "leaseInfo", "dataCenterInfo", "secureVipAddress", "metadata", "status", "ipAddr", "is_dirty", "homePageUrl", "statusPageUrl", "lastUpdatedTimestamp", "lastDirtyTimestamp", "actionType", "status_without_dirty"])

To demonstrate the problem in my fork of the service registration and discovery guide repo I've just excluded the Jersey client modules from the complete client dependencies under the complete folder as follows:

. . .
dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client') {
        exclude group: "com.sun.jersey", module: "jersey-client"
        exclude group: "com.sun.jersey", module: "jersey-core"
        exclude group: "com.sun.jersey.contribs", module: "jersey-apache-client4"
        }            
    compile('org.springframework.boot:spring-boot-starter-web')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')
}
. . .

To see this problem occurring please follow these steps:

Clone https://github.com/georgeharley/gs-service-registration-and-discovery.git
cd to the complete directory
Run ./gradlew clean build
Start the Eureka server with ./gradlew :eureka-service:bootRun
In a separate terminal start the Eureka client with ./gradlew :eureka-client:bootRun

After approximately 30 seconds the client application will attempt to fetch registry information and the error should occur for the first time. It will repeat every 30 seconds thereafter as successive cache fetch requests are made.
