Dependency hygiene

[dsyer]

Something bad happened in the upstream. Our Eureka client starter brings in servlet 2.5 (and a bunch of other crap that shouldn't be there). This is new in 3.0.0 (2.2 was OK).

[spencergibb]

do you have a dependency tree?

I think I hit this today:

javax.servlet:servlet-api:2.5
\--- com.netflix.netflix-commons:netflix-infix:0.3.0
     \--- com.netflix.netflix-commons:netflix-eventbus:0.3.0
          \--- com.netflix.eureka:eureka-client:1.10.11
               +--- org.springframework.cloud:spring-cloud-starter-netflix-eureka-client:3.0.2
               |    \--- io.pivotal.spring.cloud:spring-cloud-services-starter-service-registry:3.2.2.BUILD-SNAPSHOT:20210329.130303-8
               |         +--- runtimeClasspath (requested io.pivotal.spring.cloud:spring-cloud-services-starter-service-registry)
               |         \--- io.pivotal.spring.cloud:spring-cloud-services-dependencies:3.2.2.BUILD-SNAPSHOT:20210329.130301-8
               |              \--- runtimeClasspath
               \--- com.netflix.eureka:eureka-core:1.10.11
                    \--- org.springframework.cloud:spring-cloud-starter-netflix-eureka-client:3.0.2 (*)

This is causing our client app to blow up with:

你好，邮件已收到！

I believe this has been fixed in the recent versions.
