RegTest-test sun/nio/cs/LatinCharReplacementTWTest.java test fails intermittantly on Windows 2000 Pro with JDK1.4.2, JDKJ1.5.0.

I modified the test source to get additional information about the failure by the following way:

--------- LatinCharReplacementTWTest.java ---------
...
048> if (numChars != expected.length) {
             // !!!!!!!!!
             System.out.println("numChars=" + numChars + ", length=" + expected.length);
049> throw new Exception("failure of test for bug " + bugID);
050> }
051>
052> for (int i = 0 ; i < numChars; i++) {
053> if (decoded[i] != expected[i])
                 // !!!!!!!!!
         System.out.println("i=" + i + ", decoded=" + decoded[i] + ", expected=" + expected[i]);
054> throw new Exception("failure of test for bug " + bugID);
055 }
...
---------------------------------------------------

I got the following output of the modified testcase:

The test stable fails with JDK1.4.1, JDK1.4.0 on all platforms with another output:
