Thank you for reaching out to us.
From the call stack, I assume that the application uses the EMA message outside the EMA callback function.
Typically, the EMA messages are only valid within the EMA callback methods, such as AppClient::onRefreshMsg. To use the EMA messages outside the EMA callback methods, the application needs to clone the messages.
For example:
RefreshMsg clonedRefreshMsg
...
public void onRefreshMsg(RefreshMsg refreshMsg, OmmConsumerEvent event)
{
clonedRefreshMsg = EmaFactory.createRefreshMsg(refreshMsg);
System.out.println(clonedRefreshMsg);
}
