The java.nio.channels.FileChannel.tryLock(0L, Long.MAX_VALUE, false) throws
             IOException on Linux but works on Solaris.
Seen in JDK 1.4.0_02 (prerelease). Does not happen in 1.4.1 beta

Attaching a test case: LockTest.java


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

             public class LockTest {

                     public static final String LOCK_NAME = "domains.lck";
                     private static File STORE;

                     public static void main( String[] args ) throws FileNotFoundException {
                             boolean shared = false;
                             STORE = new File("/space/svbld", LOCK_NAME);
                             try {
                                     RandomAccessFile raf = new RandomAccessFile(STORE,
             "rws");
                                     FileChannel channel = raf.getChannel();
                                     FileLock lock = channel.tryLock(0L, Long.MAX_VALUE,
             shared);
                             }
                             catch ( IOException f ) {
                                     System.out.println("IOException caught");
                             }
                     }
             }
