Hello,
I have noticed some strange behavior with String.indexOf().
Sometimes, indexOf() returns -1 even though the argument String is
definitely in the calling String. The necessary conditions seem to be:
where:
String t,s;
t.indexOf(s);
then:
s must end with '.\r\n' (in perl: m/.\r\n$/)
t must be at least 128 characters long
s must be at the end of t
Example code:
----- BEGIN CODE -----
public class test {
public static void main(String args[]) {
String end = "a\r\n";
String text =
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\r\n";
String text2 =
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\r\n";
int iend = text.indexOf(end);
int iend2 = text2.indexOf(end);
System.err.println("Text1: length: "+text.length()+" iend:
"+iend);
System.err.println("Text2: length: "+text2.length()+" iend:
"+iend2);
}
}
----- END CODE -----
Kaffe reports an index of -1 for text1, but an index of 124 for text2.
Blackdown Java, SableVM, and JamVM all give the correct answer.
I am running Debian unstable, with kaffe version 1.1.5-3 and classpath
version 0.14-2.
If I can offer any other information please let me know.
Cheers,
Fitz
