FULL PRODUCT VERSION :
java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)


FULL OPERATING SYSTEM VERSION :

Windows NT Version 4.0



A DESCRIPTION OF THE PROBLEM :
If FileOutputStream generates an IOException, then
it should also contain the file name.
For e.g. if the disk runs out of space while writing
then, FileOutputStream class throw an IOException with
the message "There is not enough space on the disk" but
does not specify which disk.
In a simple program it is not a problem but in a complex
multi-threaded program where the application writes into
different files on different disks, the users will not
know which disk is causing the problem.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Write a small test program that continually writes into
a disk with little space.
2. Run the program and wait until the disk runs out of
space and observe the message. It will be some thing like
this ....

java.io.IOException: There is not enough space on the disk

EXPECTED VERSUS ACTUAL BEHAVIOR :
Probably the correct message should be

java.io.IOException: There is not enough space on the disk
(a:\abc.dat)
....



ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.io.IOException: There is not enough space on
the disk
        at java.io.FileOutputStream.writeBytes(Native Method)
        at java.io.FileOutputStream.write(FileOutputStream.java:212)
        at java.io.ObjectOutputStream.drain(ObjectOutputStream.java:1463)
        at java.io.ObjectOutputStream.setBlockData(ObjectOutputStream.java:1486)
        at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:407)
        at Test.main(Test.java:10)


This bug can be reproduced always.
