FULL PRODUCT VERSION :
A DESCRIPTION OF THE PROBLEM :
When set Integer.MAX_VALUE - 1 to BitSet, then call the toString method.
It will throw exception: java.lang.IndexOutOfBoundsException: fromIndex < 0: -2147483648
Test code:
public static void main(String[] args) {
BitSet bitSet = new BitSet();
bitSet.set(Integer.MAX_VALUE - 1);
System.out.println( bitSet.toString());
}
The bug was occured at 1189 line of BitSet source.
for (i = nextSetBit(i+1); i >= 0; i = nextSetBit(i+1)) {
If set Integer.MAX_VALUE to BitSet, exception will throw at the first nextSetBit(i+1). If set Integer.MAX_VALUE - 1 to BitSet, exception will throw at the second nextSetBit(i+1).
I think before call nextSetBit(i+1) method, to check i is equal to Integer.MAX_VALUE is better.
REPRODUCIBILITY :
This bug can be reproduced always.
