While trying to authenticate a Custom Connection, using the sample code, I get the following exception:

To Reproduce
Code I used:
private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();
private static final String TOKEN_REQUEST_URL = "https://identity.xero.com/connect/token";
public static final TokenStorage XERO_ERROR = null;
public static TokenStorage authenticateWithXero(XeroCredentials credentials, boolean verbose)
{
if (verbose)
System.out.println("Authenticating with Xero... ");
// The scopes that we will need
ArrayList<String> scopeList = new ArrayList<String>();
scopeList.add("accounting.transactions.read");
new NetHttpTransport();
try {
ClientCredentialsTokenRequest tokReq = new ClientCredentialsTokenRequest(HTTP_TRANSPORT, JSON_FACTORY, new GenericUrl(TOKEN_REQUEST_URL));
BasicAuthentication basicAuth = new BasicAuthentication(credentials.getClientId(), credentials.getClientSecret());
TokenResponse tokenResponse = tokReq.setScopes(scopeList)
.setClientAuthentication(basicAuth)
.execute();
if (Build.isDebug)
System.out.println(" Access token: " + tokenResponse.getAccessToken());
ApiClient defaultIdentityClient = new ApiClient("https://api.xero.com", null, null, null, null);
IdentityApi idApi = new IdentityApi(defaultIdentityClient);
List<Connection> connection = idApi.getConnections(tokenResponse.getAccessToken(),null);
// ... snip...
}
catch (TokenResponseException e) {
if (e.getDetails() != null) {
System.err.println("Error: " + e.getDetails().getError());
if (e.getDetails().getErrorDescription() != null) {
System.err.println(e.getDetails().getErrorDescription());
}
if (e.getDetails().getErrorUri() != null) {
System.err.println(e.getDetails().getErrorUri());
}
} else {
System.err.println(e.getMessage());
}
} catch (IOException e) {
System.err.println("Error: " + e.getMessage());
}
return XERO_ERROR;
}
After scratching my head for a while, I found a workaround by including the following dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-server</artifactId>
<version>2.27</version>
</dependency>
My POM file before the workaround was as follows (client details removed for privacy):
