      Description

      FULL PRODUCT VERSION :
      java version "1.5.0_06"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
      Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)

      FULL OS VERSION :
      Windows XP Professional x64 Edition

      A DESCRIPTION OF THE PROBLEM :
      #
      # An unexpected error has been detected by HotSpot Virtual Machine:
      #
      # EXCEPTION_IN_PAGE_ERROR (0xc0000006) at pc=0x6d7f3d0c, pid=1756, tid=2180
      #
      # Java VM: Java HotSpot(TM) Client VM (1.5.0_06-b05 mixed mode)
      # Problematic frame:
      # V [jvm.dll+0x113d0c]

      Stepping through the code (as far as I could) this got thrown in java.nio.DirectByteBuffer get() method while calling unsafe.getByte():

      public byte get() {
         return ((unsafe.getByte(ix(nextGetIndex()))));
      }

      THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Yes

      THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      See source code for an executable test case

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      buffer.get() should stick some bytes into the byte array file but I get an EXCEPTION_IN_PAGE_ERROR instead

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      A simple class that will reproduce this is:
      usage: java FileCopyUtil <filename>

      import java.io.File;
      import java.io.FileInputStream;
      import java.io.FileNotFoundException;
      import java.io.IOException;
      import java.nio.MappedByteBuffer;
      import java.nio.channels.FileChannel;
      import java.nio.channels.FileChannel.MapMode;

      public class FileCopyUtil {

      public FileCopyUtil() {

      }

      /**
      * @param args
      */
      public static void main(String[] args) {
      File src = new File(args[0]);

      try {
      byte[] file = new byte[(int) src.length()];
      FileChannel channel = new FileInputStream(src).getChannel();
      MappedByteBuffer buffer = channel.map(MapMode.READ_ONLY, 0, src.length());
      buffer.get(file);
      } catch (FileNotFoundException e) {
      e.printStackTrace();
      } catch (IOException e) {
      e.printStackTrace();
      }
      }

      }
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Use InputStreams into of channels
