> In the BitArrayBin, the index's unit type is long. It also has a variable called firstIndex,
which store 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 will cause activemq client to perform badly when receiving message that sequence
id is bigger than max interger. Below is the jstack log that shows the problem.
