if ((opQueue = opQueueMap.get(queueId)) == null) {
You write this way although it looks cleaner, but it is not easy to read the code

Assigning opQueue at first may be better than initializing it in if condition.

Ok, I think this can reduce one query, although the time complexity is only O(1) and I don't think it's a good practice to judge first and then get it. If the opQueueMap has a removal operation, there will be problems.
