Null pointer exception in RFA TS1 (7.6.1.L1), when decoding time series

Hello, I am getting null pointer exceptions from TS1 when decoding time series data for some RICs, for example for "3398.HK"

I checked the TimeSeriesTrend.java TS1 example in the SDK and with 90 samples it also throws the exception. Java RFA SDK 7.6.1.L1 (Legacy examples).

Can someone please help?, stack trace from TimeSeriesTrend example below

Thanks

Hi @Wasin Waeosri,

Are you able to share any update on this?

... extending triage by one week.

Hi @tdlc

Please be informed that the issue has been fixed in RFA Java 7.6.1 E1. I did a quick test and the TimeSeriesTrend example can display data successfully without any error messages.

You can download the API from Developer Portal RFA Java Download page.

@tdlc, I tried that instrument with RFA Java 8.x and can get data without issues. See attached screenshot:

Hello @tdlc,

I just tested example TimeSeriesTrend and was able to retrieve and to chart 3398.HK.

Firstly, if you are looking to retrieve time series data, I would not use this legacy example that uses deprecated interfaces and GUI, but instead, use a simpler OMM TimeSeriesConsole example.

If you require to use this specific example, I would make sure that the session you are passing is an SSL session, not RSSL, that user is permissioned via DACS to the content being requested, and that Market Data (not OMM) data dictionaries are either requested from the infra or, if loaded locally, are 100% in synch with the market data dictionaries on the infrastructure.

@Gurpreet.

@zoya.farberov

Thanks for the reply. The GUI is able to display some data, but you still get the exception on stderr (unless our problem is in our TREP installation).

Could you please send the messages printed to the stderr/stdout by the example so I can compare?

To clarify, I checked the TimeSeriesTrend example because we get this exception in our application, I am not writing a new application, I just wanted to make sure our application was decoding the data in the right way, and it is doing exactly the same as in the example.

Unfortunately migrating to OMM is currently not an option, that's why the need to make this work properly with this specific version of RFA.

Thanks in advance

@tdlc,

We do not get any exceptions or errors on the run.

If the problem did not manifest until recently, I would look for what have changed. The programmatic changes first, the configuration changes second, the infrastructure updates next, check with your market data team on this.

There are no miracles in computer science :), therefore something must have changed, and sometimes, it can be very challenging to track the change, we understand!

tdlc zoya faberov May 22, 2019 at 11:57 AM

The fact that the examples (TimeSeriesTrend and now TimeSeriesConsole) and the application fail in the same way, makes me suspect that the problem is in TREP.

I'll get in touch with support.

Thanks again

How can I get the dictionaries on the infrastructure?, where are they located?

Hello @tdlc

The API development team can replicate the issue with the same RFA Java example. The team is working on this issue.
