about DrivingQueryItemReader's question

[cuizuoli]

When I used DrivingQueryItemReader, I setted saveState propertie is true, When DrivingQueryItemReader call update(ExecutionContext executionContext) method, call getCurrentKey();
protected Object getCurrentKey() {
if (initialized) {
return keys.get(currentIndex - 1);
}

return null;
}
now it throw java.lang.ArrayIndexOutOfBoundsException: -1 exception.
I debug it, I find that Step first call update(ExecutionContext executionContext), then call read(), the currentIndex properties is 0, the following code:
return keys.get(currentIndex - 1);
is that:
return keys.get(0 - 1);
so, throwing exceptions.
Other persons occur this question?
