Bug in String.lastIndexOf

There's a bug in java.lang.String lastIndexOf(String, int).
Here's a short test program that illustrates the problem:
class t
{
public static void main(String[] args)
{
String s1 = "this is a test yes it is";
String s2 = "yet another test";
String s3 = s2.substring(12); // "test"
for (int i = 0; i < s1.length(); i++)
System.err.println("i = " + i + " index = " + s1.lastIndexOf(s3, i));
}
}
If you run this program with kaffe (current CVS), the
lastIndexOf call returns 10 for -all- values of i.
It should return -1 for i < 10 (and does so with IBM 1.3, for
example).
