NonSuccessfulResponseCodeException: Bad response: 400

I was tried to call in my main class

signalService.finishConnectAsPrimary(verCode);

but this error occurs:

Exception in thread "main" org.whispersystems.signalservice.api.push.exceptions.NonSuccessfulResponseCodeException: Bad response: 400 at org.whispersystems.signalservice.internal.push.PushServiceSocket.makeServiceRequest(PushServiceSocket.java:894) at org.whispersystems.signalservice.internal.push.PushServiceSocket.makeServiceRequest(PushServiceSocket.java:791) at org.whispersystems.signalservice.internal.push.PushServiceSocket.verifyAccountCode(PushServiceSocket.java:223) at org.whispersystems.signalservice.api.SignalServiceAccountManager.verifyAccountWithCode(SignalServiceAccountManager.java:203)

any idea?

i'm using jdk 1.8

futhermore, here is my implementation code which already modified little bit according to the new version of signal-service-java version

public void finishConnectAsPrimary(String verificationCode) throws IOException {
        if(accountManager == null) {
            throw new IllegalStateException("Cannot finish: No connection started!");
        } else if(isRegistered()) {
            throw new IllegalStateException("Already registered!");
        }
        createRegistrationId();
        byte[] signalingKey = new byte[52];
        SecureRandom secureRandom = new SecureRandom();
        secureRandom.nextBytes(signalingKey);
        byte[] secret = new byte[32];
        secureRandom.nextBytes(secret);
        byte[] unidentifiedAccessKey = UnidentifiedAccess.deriveAccessKeyFrom(secret);

        accountManager.verifyAccountWithCode(verificationCode, store.getSignalingKey(),
                store.getLocalRegistrationId(), false, PIN, unidentifiedAccessKey, true);
        IdentityKeyPair identityKeyPair = KeyHelper.generateIdentityKeyPair();
        store.setIdentityKeyPair(identityKeyPair);
        checkPreKeys(-1);
        save();
    }
