RMSample ConnectionClosedException Exception

OSLC implementations
5

I just checked the code of processPagedQueryResults and I would modify it in the following way:

try {

	//Get a single artifact by its URL
	response = client.getResource(resultsUrl, OSLCConstants.CT_RDF);
	boolean processed = false;

	if (response != null) {
		//De-serialize it as a Java object
		if (asJavaObjects) {
			   //Requirement req = response.readEntity(Requirement.class);
			   //printRequirementInfo(req);   //print a few attributes
		} else {

			//Just print the raw RDF/XML (or process the XML as desired)
			processRawResponse(response);
			processed = true;
		}
	}
	if (!processed && response != null) {
		// discard the result
		response.readEntity(String.class);
	}
} catch (Exception e) {
	logger.log(Level.SEVERE, "Unable to process artfiact at url: " + resultsUrl, e);
}

AFAIK, the idea is that the response must be processed even if you don’t need it. Sometimes, we had problems with just calling close (i.e. exceptions). I think AHC 5 also implements AutoCloseable to avoid dealing with these low-level details.

P.S. Jakarta Response does implement AutoCloseable but Java EE 7 JAX-RS doesn’t.
