zht0209 opened a new issue #9325:
URL: https://github.com/apache/shardingsphere/issues/9325
public synchronized long getEndIndex(final long fromIndex, final int size) {
if (size == 0) {
return fromIndex;
}
int correctIndex = (int) (fromIndex - startIndex);
int listIndex = correctIndex / BIT_SET_SIZE;
int count = size;
for (int i = listIndex; i < bitSets.size(); i++) {
int begin = i == listIndex ? correctIndex % BIT_SET_SIZE : 0;
for (int j = begin; j < BIT_SET_SIZE; j++) {
if (bitSets.get(i).get(j) && --count == 0) {
return startIndex + i * BIT_SET_SIZE + j + 1;
}
}
}
throw new IndexOutOfBoundsException(String.format("BitSets(%s) do
not have enough data from %d count %d", bitSets, correctIndex, size));
}
当fronIndex< startIndex，listIndex会小于0
