Cannot invoke "org.springframework.cloud.netflix.eureka.CloudEurekaClient.getApplications() when Jersey Client on classpath

[weiro-9-w7]

Describe the bug
I view the document , but I want to know how to config it when we have the resttemplate & Jersey.

Sample
I write a demo to show the issue,
The demo contains eureka server & two eureka clients.
The client 02 only more dependency than client 01:

    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>
        <version>3.1.5</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-common</artifactId>
        <version>3.1.5</version>
    </dependency>

the client 01 starts normally, but the client 02 throw exception:

Hello @weiro-9-w7, thanks for reporting the issue. As @krezovic has suggested, this looks like a duplicate of #4185 . Please verify against SC Netflix 4.1.3 with eureka.client.jersey.enabled set to false.
