FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

A DESCRIPTION OF THE PROBLEM :

Please see:
http://java.sun.com/j2se/1.4/docs/api/java/util/regex/Matcher.html#appendReplacement(java.lang.StringBuffer, java.lang.String)

The example given for the method appendReplacement(..., ...)
in java.util.regex.Matcher is:

Pattern p = Pattern.compile("cat");
Matcher m = p.matcher("one cat two cats in the yard");
StringBuffer sb = new StringBuffer();
boolean result = m.find();
while (m.appendReplacement(sb, "dog")) {
    result = m.find();
}
m.appendTail(sb);
System.out.println(sb.toString());

This is obviously wrong and won't even compile. This
should most probably be:

Pattern p = Pattern.compile("cat");
Matcher m = p.matcher("one cat two cats in the yard");
StringBuffer sb = new StringBuffer();
while (m.find()) {
     m.appendReplacement(sb, "dog");
}
m.appendTail(sb);
System.out.println(sb.toString());


This bug can be reproduced always.
