java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)


FULL OPERATING SYSTEM VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
On Windows, after opening all available file handles, an
attempt to open a file using RandomAccessFile will delete
the file you are attempting to open.  The following simple
test program creates 5000 files in a directory supplied on
the command line and then attempts to open all of them at
the same time.  You will note at the pause that all of the
files exist.   After we have tried to open all of the files
most of them will have been deleted.  This does _not_ remove
the files in version 1.4.0_02.

The problem report is for java.io.RandomAccessFile.  When just
creating java.io.File objects the problem does _not_ occur.  When
opening the file using java.io.FileInputStream the files get deleted
just like java.io.RandomAccessFile.  The only way that I could open
the files using java.io.DataInputStream was by using
java.io.FileInputStream, which evidenced the problem.


REGRESSION.  Last worked in version 1.4

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Run the java program supplied.
2.At the pause, you will note that there have been 5000
files created.
3.You will get a bunch of errors unable to open file when
file handles have been exausted.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED:
All of the files created still exist.

ACTUAL:
Most of the files were deleted just by attempting to open them.


REPRODUCIBILITY :
This bug can be reproduced always.
