FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
When launching a Java Web Start application that requires a JRE that is not currently installed on the user's PC, the autodownload fails 75% of the time.

At seemingly random intervals, various errors can occur, but the most prevalent is the Web Start client receiving an HTTP response code: 500 from sun's servers when attempting to autodownload a runtime environment.

Note that this seems to be a problem with the autodownload servlet, more than with a particular Web Start version. I have reproduced the problem with Web Start v1.0.1_02, 1.2.0, and 1.4.2. (some of the actual results/stack traces are from webstart 1.0.1_02 attempting to download JRE 1.4.2 - and labelled as such).

This problem has been occuring for approximately 1 month.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a JNLP file that requires a specific JRE

ie. <j2se version="1.4.2" href="http://java.sun.com/products/autodl/j2se"/>
or
     <j2se version="1.4.1" href="http://java.sun.com/products/autodl/j2se"/>

2. Launch the application from a PC that does not have that version of the JRE installed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect that the requested JRE will be installed on the PC.
ACTUAL -
Random Download Errors of two different types:

1) HTTP response code 500

CUSTOMER SUBMITTED WORKAROUND :
Not much of a workaround, but typically after attempting to launch the application between 5 and 20 times, the JRE will successfully download.
