JNLP TCK tests sometimes fail when run under Windows platform
(but sometimes pass)

The log file contains following strange lines for these failures:

Logging to file: D:\JNLP-TCK\javaws.log
#### Java Web Start Error: #### javasoft.sqe.tests.http.requests.VersionBasedProtocol.version_plusTests
Java Web Start Console, v1.0-rc started Fri Jun 16 19:26:47 GMT+04:00 2000

##TCKHarnesRun##:961172176724:503498:Thread[main,5,main]:JNLP Launching
Failed. The jnlp client exit code is -1

To reproduce this problem just run JNLP TCK on windows.
The list of failed tests changes from run to run

The root of the problem is concurrency writing to the cache directory
files with same names.

to reproduce the problem use the standard example
draw.jnlp

#run javaws
WIN> javaws.exe http://matmech:8080/draw.jnlp
# quickly change modified time for draw.jar and draw.jnlp
matmech> touch draw.jar draw.jnlp
# run quickly javaws with the same url one more time
WIN>javaws.exe http://matmech:8080/draw.jnlp

If your http server do not generate Last-Modified field, or generate it incorrectly you can only run jnlp client two times.
Some times one of the running applications hangs up,
some times generate error message:

An error occurred while launching/running the application.
