> Since TOMEE-4716, {{RESTService}} deploys the MicroProfile Health endpoint ({{MicroProfileHealthChecksEndpoint}}) in its own {{InternalApplication}} at the context root when the webapp declares JAX-RS applications, but none at the context root.
> That application is deployed with {{additionalProviders}}, the collection that the loop over the declared applications fills with the providers each one lists in {{getClasses()}} / {{getSingletons()}}. So a provider meant for one application, e.g. an unbound {{@PreMatching}} {{ContainerRequestFilter}} of an application at {{/api}}, also runs for {{/health}}, {{/health/live}}, {{/health/ready}} and {{/health/started}}.
> With a filter that aborts every request it doesn't recognize, all health endpoints answer with that filter's response instead of the health checks. Seen with an MCP server application whose pre-matching filter answers {{503}} with an empty body outside its own application: every {{/health}} request returns {{503}}, and the endpoint method never runs.
> Fix: deploy the container application with only the webapp-wide providers, those collected before the declared applications add their own.
