spring hateoas 1.1.0 base rel path getting truncated

Question

I have recently upgraded our application into Spring Boot 2.3.2.RELEASE which uses Spring Hateoas 1.1.0.RELEASE.

My base rel path for any link is: "urn:eim:linkrel:"

With Spring Boot 2.2.6.RELEASE, the response is like below:

{
    "_links": {
        "urn:eim:linkrel:users": {
            "href": "https://localhost:8080/v1/users"
        }
    }
}

With Spring Boot 2.3.2.RELEASE, the response changed like below:

{
    "_links": {
        "urn:eim": {
            "href": "https://localhost:8080/v1/users"
        }
    }
}

My code to generate the above response:

import javax.servlet.http.HttpServletRequest;

import org.springframework.hateoas.Link;
import org.springframework.hateoas.RepresentationModel;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DemoController {

    @RequestMapping(value = "/service", method = RequestMethod.GET, produces = "application/hal+json")
    public HttpEntity<RepresentationModel<?>> service(HttpServletRequest request) {
        
        RepresentationModel<?> service = new RepresentationModel<>();

        service.add(Link.of("https://localhost:8080/v1/users", "urn:eim:linkrel:users"));

        return new ResponseEntity<>(service, HttpStatus.OK);
    }
}

Does anyone has similar issue? Can anyone please let me know the solution to fix this issue.

According to Github issue, this issue (support multiple colons) is fixed and is going to be release in milestone 1.2.0-M1.

I see the fix commit is in branch 1.1.x. I guess the fix may be included in fix version 1.1.1.
