Only one health group can be exposed using management.endpoint.health.group.xxx.additional-path=server:/newpath when using Jersey

Lines 50 to 64 in f978051

	@Override
	protected Resource createResource(EndpointMapping endpointMapping, WebOperation operation) {
	WebOperationRequestPredicate requestPredicate = operation.getRequestPredicate();
	String matchAllRemainingPathSegmentsVariable = requestPredicate.getMatchAllRemainingPathSegmentsVariable();
	if (matchAllRemainingPathSegmentsVariable != null) {
	for (HealthEndpointGroup group : this.groups) {
	AdditionalHealthEndpointPath additionalPath = group.getAdditionalPath();
	if (additionalPath != null) {
	return getResource(endpointMapping, operation, requestPredicate, additionalPath.getValue(),
	this.serverNamespace, (data, pathSegmentsVariable) -> data.getUriInfo().getPath());
	}
	}
	}
	return null;
	}

When using Spring Boot with both Jersey and Actuator, the health endpoint only allows one health group to have an additional-path configured. All other additional paths are ignored except for the first that appears in the configuration file.

management.endpoint.health.group.liveness.additional-path=server:/health1
management.endpoint.health.group.readiness.additional-path=server:/ready1

Only /health1 will be available as a JAX-RS Resource. The available health endpoints will be:

• /actuator/health/liveness
• /actuator/health/readiness
• /health1

I suspect the fix will be to override the JerseyEndpointResourceFactory.createEndpointResources method instead of only overriding createResource.

It would be much easier to write the fix if this code were written using a normal loop instead of the streams API:

spring-boot/spring-boot-project/spring-boot-actuator/src/main/java/org/springframework/boot/actuate/endpoint/web/jersey/JerseyEndpointResourceFactory.java

Lines 87 to 90 in f978051

	endpoints.stream()
	.flatMap((endpoint) -> endpoint.getOperations().stream())
	.map((operation) -> createResource(endpointMapping, operation))
	.forEach(resources::add);

Then it would be trivial to add more than one Resource per endpoint.
