4-5 test case related to java.util.prefs and java.nio.channel
are failing, seeing the error code, it is related to file locking.

Tested these tests on Build-59

Sample Code for java.util.prefs

import java.util.prefs.*;
import java.util.*;
 

public class Test20 {
     
    public void check1() {
         try {
           Preferences userRoot = Preferences.userRoot();
           userRoot.put("Test","Libs");
           userRoot.flush();
           System.out.println("The vale got back is :"+userRoot.get("Test","Default"));
          } catch(Exception e) {
            e.printStackTrace();
          }
       
    }
    
 
    
    public static void main(String[] args) throws Exception {
      Test20 ref = new Test20();
      ref.check1();
      
     }
 

}


Sample code for File Locking
Before Running this test create any file by name Sample.txt

import java.io.*;
import java.nio.channels.*;
import java.nio.*;

public class Test21 {

   public boolean check() throws Exception {
        boolean bReturn = true;
        RandomAccessFile raf = null;
        FileChannel c = null;
        File tempFile = new File("Sample.txt");
        tempFile.deleteOnExit();
        try {
           raf = new RandomAccessFile(tempFile,"rw");
           c = raf.getChannel();
           FileLock fl1 = c.lock(0,c.size(),true);
FileChannel fc = fl1.channel();
if(!fc.equals(c)) {
  bReturn = false;
                System.out.println("channelTest01: FAIL.");
           }
fl1.release();
c.close();
        } catch (Exception e) {
           bReturn = false;
           e.printStackTrace();
        }

        return bReturn;
       
   }
   
    
   
   public static void main(String args[]) {
       Test21 ref = new Test21();
       try {
         System.out.println("Test For File Channel Passed "+ref.check());
       } catch(Exception e) {
          e.printStackTrace();
       }
   }
}


----------------------------------------------
I executed both the test cases on AMD64 with RH AS-3
Red Hat Enterprise Linux AS release 3 (Taroon)
Kernel 2.4.21-4.EL on an x86_64

Both the test cases passed,
On Intel arch with RH AS-3 it works fine.

I am seeing the failure on ALSES-8

In addition to above information:-
Test case Test21 passes on AMD64 SLES-8
if we copy the test case to local directory
over the NFS it fails.

Whereas the test case Test20 fails even if copied
and executed from local directory.
