REST Path("/") conflicts with app [message #1785265]

I use eclipselink to enable JSON marshalling with JAXB (org.eclipse.persistence.jaxb). I don't use for JPA or REST.

Deploying apps to Kubernetes (GKE) requires the root path to return HTTP 200 for a health check. I have basic code for that:

@GET
@Path("/")
public String checkHealth() {
return "OK";
}

However, at runtime, this conflicts with

public javax.ws.rs.core.Response org.eclipse.persistence.jpa.rs.resources.unversioned.PersistenceResource.getContexts(javax.ws.rs.core.HttpHeaders,javax.ws.rs.core.UriInfo)

which also declares:

@Path(value="/")

WildFly chooses this instead of the application's checkHealth(), resulting in an Internal Server Error, causing health check to fail, and application to complete deployment in Kubernetes.

I noticed this is deprecated but still in 2.7. It is not clear if its replacement would correct this issue, which uses this path:

@Path(value="/{version : v\\d\\.\\d|latest}/")

What is the easiest way to remedy this? Was it critical for eclipselink to use the root path?

If there was a separate JAXB library I'd just use that. Unfortunately, I'm getting JPA REST even though I have no interest in it.
