Hyperledger Fabric Java Chaincode Timeout Expired While Starting Chaincode

I am running Hyperledger Fabric v2.2.3 in Oracle Linux 8, and trying to run Java chaincode using External Builder and Launcher method. I have no idea at which point I am doing wrong or configure wrong. By invoking the chaincode via cli, and after waiting quite some time, about 15 mins, it always giving out chaincode registration failed: timeout expired while starting chaincode. It seems to me not able to connect or reached my chaincode, but seems my suspicious is wrong, if not reaching, my chaincode log wont have any debugging info as below.

Here is my committed chaincode in my peer:

[user@hyperledgerfabric ~]# /appl/hyperledger-fabric/bin/peer lifecycle chaincode queryapproved -C orderer-channel -n TestHLF --peerAddresses localhost:7051 -o localhost:7050

Approved chaincode definition for chaincode 'TestHLF' on channel 'orderer-channel':

Committed chaincode definition for chaincode 'TestHLF' on channel 'orderer-channel':
Version: 1.0.0, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc, Approvals: [MyOrg1: true]

connection.json:

{
  "address": "192.168.196.1:9999",
  "dial_timeout": "10s",
  "tls_required": false,
  "client_auth_required": false
}

My Java Chaincode (running at 192.168.196.1):

@Contract(
  name = "TestHLF",
  info = @Info(
    title = "Testing Hyperledger Fabric",
    description = "Testing Hyperledger Fabric",
    version = "1.0.0",
    license = @License(
      name = "Apache 2.0 License",
      url = "http://www.apache.org/licenses/LICENSE-2.0.html"
    ),
    contact = @Contact(
      email = "[email protected]",
      name = "Test",
      url = "https://test.example.com"
    )
  )
)

@Default
public final class TestHLF implements ContractInterface {
  @Transaction()
  public void init(Context context) {
    // do nothing
  }

  @Transaction(intent = TYPE.EVALUATE)
  public void insert(Context context, String key, String val) {
    ChaincodeStub stub = context.getStub();
    stub.putStringState(key, val);
  }

  @Transaction(intent = TYPE.EVALUATE)
  public String retrieve(Context context, String key) {
    ChaincodeStub stub = context.getStub();
    String val = stub.getStringState(key);
    return val;
  }

  public static void main(String[] args) throws Exception {
    ChaincodeServerProperties props = new ChaincodeServerProperties();
    props.setPortChaincodeServer(9999);
    props.setTlsEnabled(false);

    ContractRouter router = new ContractRouter(new String[] { "-i", "TestHLF:9081c95c231420aff76d311b14ae0eb468c199ee7aecea6e74934b588e3a3672", "-a", "192.168.196.134:7052" });
    ChaincodeServer server = new NettyChaincodeServer(router, props);
    router.startRouterWithChaincodeServer(server);
  }
}

Once I started my Java chaincode, the log here printed in the console:

Invoking the chaincode via cli, and here are the debug log:

I miss the CCID of the chaincode. Not really sure about Java API (I'm more into Go API), but it should be specified somewhere. You can try with...

    ContractRouter router = new ContractRouter(new String[] { "-i", "TestHLF:9081c95c231420aff76d311b14ae0eb468c199ee7aecea6e74934b588e3a3672", "-a", "192.168.196.134:7052" });

...although I think it expects simply "TestHLF". It does not seem to be documented for Java... https://hyperledger-fabric.readthedocs.io/en/release-2.2/cc_service.html#writing-chaincode-to-run-as-an-external-service

I've taken the CCID directly from your peer's error logs.
