The following code shows an error in BitSet.and:

//--------------------------------------------------------------------------------------

import java.util.*;

public final class Test
{
public static void main(String[] args)
{
BitSet a = new BitSet();
BitSet b = new BitSet();

a.set(0);
b.set(1);

a.and(b);

System.out.println(a + " " + a.length());
}
}

//--------------------------------------------------------------------------------------

The output is "{} 1" instead of "{} 0".

It seems that the internal data structure of BitSet is inconsistent.
(Maybe recalculateUnitsInUse() at the end of BitSet.and fixes it.)
