Do you have any idea on the following NullPointerException? It occurred after we uninitialized and then new OmmConsumer due to got the 'CLOSED' login StatusMsg after the application has been running a while. However hard to be reproduced. If you know the possible root cause and how to avoid it? Thanks.

    @Frederic

    Thank you for reaching out to us.

    Please check the version of EMA used by the application. The latest version is RTSDK 2.2.1.L1 (EMA/ETA 3.8.2.L1).

    If the application uses the old version, please upgrade the application to use the latest version. The latest version is available on the Software Downloads. It is in the MDS - API product family.

    If the problem still persists in the latest version, please contact the API support team directly via Contact Premium Support.
