@Path mismatch on quarkus-rest vs quarkus-resteasy with regex

[jorsol]

Describe the bug

When @Path("{name: [a-z0-9]+((\\.|_|__|-+)[a-z0-9]+)*(\\/[a-z0-9]+((\\.|_|__|-+)[a-z0-9]+)*)*}/hello") is used on a rest endpoint, with the quarkus-rest (reactive) extension, it does not match paths like "/lib/proj__ect-v1.0/hello/" and the endpoint is not found (404).

Expected behavior

Using quarkus-resteasy (classic) it does match correctly.

It should match the regular expression and find the endpoint correctly, at least it should behave consistently with quarkus-resteasy.

Actual behavior

On quarkus-rest it does not match returning a 404.

How to Reproduce?

Change between quarkus-resteasy and quarkus-rest:

@Path("/")
public class GreetingResource {
    @Path("{name: [a-z0-9]+((\\.|_|__|-+)[a-z0-9]+)*(\\/[a-z0-9]+((\\.|_|__|-+)[a-z0-9]+)*)*}/hello")
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String hello(@PathParam("name") String name) {
        return "Hello " + name;
    }
}

@QuarkusTest
class GreetingResourceTest {
    @Test
    void testHelloEndpoint() {
        given()
        .when().get("/lib/proj__ect-v1.0/hello/")
          .then()
             .statusCode(200)
             .body(is("Hello lib/proj__ect-v1.0"));
    }
}
