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
