> In BitArrayBin class, the index's unit type is long. It also has a variable called firstIndex, which store the index where the window starts. And that firstindex's unit is int. If the index is bigger than Integer.MAX_VALUE, setBit() and getBit() starts to return bad value.
> The defect causes activemq client to perform badly when receiving message that sequence id is bigger than max interger. It spends most of the time to shift window, and also blocks other consumer threads. Below is the jstack log that shows the problem.
