ServletEndpoints should not register under the Jersey context path if there is a management port

[zuckel]

In Spring Boot 2.1.2 (since 2.0.7) with a Jersey webapp, a @ServletEndpoint will be registered under the jersey context-path even on the management port.

Current behavior

If the configuration looks like this,

@ApplicationPath("/app")
public class JerseyConfig extends ResourceConfig {

@ServletEndpoint(id = "selftest")
public class SelftestEndpoint implements Supplier<EndpointServlet> {

server.port: 8080
management.server.port: 8081

the actuator will be registered under http://localhost:8081/app/actuator/selftest.

The actuator overview http://localhost:8081/actuator lists the actuator under http://localhost:8081/actuator/selftest.

Expectations

• All actuators should be reachable following the links from the actuator overview.
• If there is a management port, all actuators should sit directly under the same actuator context-path.
