FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b14)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b14, mixed mode)

FULL OPERATING SYSTEM VERSION :

Microsoft Windows 2000 [Version 5.00.2195]

ADDITIONAL OPERATING SYSTEMS :

N/A

EXTRA RELEVANT SYSTEM CONFIGURATION :
Nothing special, pure java.util.regex issue.

Problem occurs with both client and server VMs.

A DESCRIPTION OF THE PROBLEM :
Using Pattern and Matcher in java.util.regex to replace CR
(regex '$') with some other String, Java 1.4.0 works fine
but 1.4.1 beta matches on almost every character, rather
than just end-of-line chars.

REGRESSION. Last worked in version 1.4

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the example code with Java 1.4.0_01 and Java 1.4.1
beta
2. Compare actual and expected output.


EXPECTED VERSUS ACTUAL BEHAVIOR :
With 1.4.0_01 I get (good):

was: first bit
second bit
is : first bitCRsecond bitCR

With 1.4.1 beta I get (bad):

was: first bit
second bit
is : CRfCRiCRrCRsCRtCR CRbCRiCRtCR
CRsCReCRcCRoCRnCRdCR CRbitCR


ERROR MESSAGES/STACK TRACES THAT OCCUR :
No exceptions or errors, just incorrect output.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.regex.*;

public class DollarTest {

public static void main(String[] args) {

Pattern findCR = Pattern.compile("$", Pattern.MULTILINE);

String testString = "first bit\nsecond bit";

Matcher matcher = findCR.matcher(testString);
String output = matcher.replaceAll("CR"); // I do mean the String "CR"

System.out.println("was: "+testString);
System.out.println("is : "+output);
}
}

---------- END SOURCE ----------

CUSTOMER WORKAROUND :
Not worked out one yet, will stick to Java 1.4.0_01 for the
moment.

Release Regression From : 1.4.0_01
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
