    else if (streamId != 0)
        throw new ConnectionException(CancelReasonCode.INVALID_STREAM_ID, streamId, "streamId on ping needs to be 0 but was=" + streamId);
    // TODO: Verify this, previous code looks like connectionlevel = false but shouldn't this be true
    PingFrame frame = new PingFrame();
    super.unmarshalFrame(state, frame);
    byte flags = state.getFrameHeaderData().getFlagsByte();
    frame.setIsPingResponse((flags & 0x1) == 0x1);
    ByteBuffer payloadByteBuffer = bufferPool.createWithDataWrapper(framePayloadData);
    frame.setOpaqueData(payloadByteBuffer.getLong());
    bufferPool.releaseBuffer(payloadByteBuffer);
    if (frame.getStreamId() != 0)
        throw new IllegalArgumentException("PingFrame can never be any other stream id except 0 which is already set");
    return frame;
