IndexOutOfBoundsException at registerClient EMA :

API EMA 3.6.3.1

JAVA

Windows

We experience since this morning (May the 9th) an IndexOutOfBoundsException when trying to use registerClient.

The source code, library and configuration file have not changed since April, the 28th.

Can you check please ? And can you give us the reason why we got this exception ?

Here under the complete stack trace of this exception:

11:38:39 processRTDSEvents:3644 failed!

Hi,

Please , consider this issue as closed as i discovered a very strange behaviour at the start of my process that explain why the regisiterClient has thrown a IndexOutOfBoundsException.

It is our fault.

My apologize,

Jean,

Hello @jean.questiaux

Thank you for contacting us. To let us check the issue in more detail, could you please give us the following information?

The snippet code that creates a request message and calls registerClient() method
Java SDK version
Are you connecting to the local RTDS or RTO (cloud)?
Number of items that the application subscribes to

The EMA 3.6.3.1 (RTSDK 2.0.3.L2) is quite old, so if you can replicate the issue on demand, I recommend you retest with the latest version of the SDK. You can download the latest SDK version from the RTSDK Java download page.

Java version is

java version "11.0.12" 2021-07-20 LTS

belfius.firt.rtdsdownload.zip is a the snippet asked with the call to registerClient

I am connecting to a local RTDS. see TREP connection.

For a week (28/4 till last FRiday), i use RTDS without problem to this PRD server with same credentials, source code and configuration.

I will upgrade my EMA lib in user acceptance to use this one.

Thanks,

Hello @jean.questiaux

I have checked the file. The application sends a single item message with View multiple times. The EMA's related code looks fine.

For further investigation, I highly recommend you contact the Real-Time APIs support team (RDC) to investigate this issue in detail. You can submit a support ticket to the team via the "Contact premium support" button on the RTSDK Java page.
