Following is the Advisor code:
public class DeliverWhenReviewCompletedInTR extends AbstractScmService implements IOperationAdvisor {
    IRepositoryItemService itemService;  
    @Override
    public void run(AdvisableOperation operation, IProcessConfigurationElement advisorConfiguration, IAdvisorInfoCollector collector, IProgressMonitor monitor)         throws TeamRepositoryException {
        Properties prop = new Properties();
        try {   
            prop.load(new FileInputStream("config.properties"));
        } catch (IOException ex) {
            ex.printStackTrace();
        }
       
        Object operationData = operation.getOperationData();
        if (!(operationData instanceof DeliverOperationData)) {
            return;
        }
        DeliverOperationData data = (DeliverOperationData) operationData;
        List<IChangeSetHandle> changeSetHandles = data.getChangeSetHandles();

        itemService = getService(IRepositoryItemService.class);
        RestClient client = new RestClient();
        Resource resource = client.resource(prop.getProperty("TeamReviewServerURL") + "/rtcArtifact");
        List<String> rtcArtifactUuids = new ArrayList<String>();
        for (IChangeSetHandle iChangeSetHandle : changeSetHandles) {
            rtcArtifactUuids.add(iChangeSetHandle.getItemId().getUuidValue());
        }
        MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl<String, String>();
        queryParams.put(RtcArtifact.QueryParams.CHANGESET_UUID.name(), rtcArtifactUuids);
        resource.queryParams(queryParams);
        ClientResponse response = resource.contentType("text/plain").accept("text/plain").get();
        //Handle response here...
    }  
}

Tried testing the precondition with different versions of JTS:

a. 4.0.3 :- the provision status shows "the bundle could not be resolved" for the precondition. Searched this on jazz forum to find a similar question (https://jazz.net/forum/questions/126661/crjzs0383e-the-test-bundle-could-not-be-resolved). This question also noted this : I have not faced such issue with RTC 3.x and RTC 4.0.1 but facing for RTC 4.0.3.

Also tried writing a simple HelloWorld kind-of precondition and delploying it on the same server. But this also resulted in the same error - bundle could not be resolved.

b. 3.0.1.3 :- on this server, with the zip I found on the machine \\9.184.167.152\e$, after deploying the precondition, requestResetting, and restarting the server, the CCM application becomes unavailable. Any references to CCM result in 404 error.

c. 4.0.4 :- installed 4.0.4 from the repository on machine 9.184.167.152.  On starting the server, on the steps, deploying JTS and CCM applications, following exception is thrown, although the server starts

Tried uninstalling and installing this server multiple times, but the same exception resulted. As the server started with this error, I provisioned my precondition and did requestReset. Now, on restarting the server, I again get the same exception and the CCM application becomes unavailable, and all the URLs related to CCM result in HTTP 404.
