Null pointer exception while setting a deadline on a stub

I posted this on the grpc mailing list too, reposting here because I’m not sure what the right forum is.

I followed directions in this issue to add deadlines to a RPC. But I get a null pointer error. java.lang.NullPointerException at io.grpc.stub.AbstractStub.withDeadlineAfter(AbstractStub.java:117)

My code is blockingStub.withDeadlineAfter(10, TimeUnit.DAYS).doSomething()

Can the callOptions here be null by any chance?

   * Returns a new stub with a deadline that is after the given {@code duration} from now.
   *
   * @see CallOptions#withDeadlineAfter
   */
  public final S withDeadlineAfter(long duration, TimeUnit unit) {
    return build(channel, callOptions.withDeadlineAfter(duration, unit));
  }

I’m using the code generated by the protobuf java plugin and the constructor initializes callOptions to CallOptions.DEFAULT, so I’m not sure what’s wrong here. Anyone else faced this issue? I’m using protobuf-gradle-plugin:0.7.6.

   * Constructor for use by subclasses, with the default {@code CallOptions}.
   *
   * @param channel the channel that this stub will use to do communications
   */
  protected AbstractStub(Channel channel) {
    this(channel, CallOptions.DEFAULT);
  }

@shishir127 no worries 😃. Only thing, next time you report a bug,please include the gRPC version and extra points if you also include a reproducer!

Thanks

@buchgr So I dug a bit deeper and realized mocks were used somewhere during a test setup which was definitely the cause for the NPE 😞 😓 . Sorry for the trouble.
