EMA Java: NPE after uninitialize and then re-new the OmmConsumer

Frederic

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.
