FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :Microsoft Windows 2000
[Version 5.00.2195]


ADDITIONAL OPERATING SYSTEMS : Linux (using file 'j2re-
1_4_0_01-linux-i586.bin' to install the JRE and Java Web
Start)

EXTRA RELEVANT SYSTEM CONFIGURATION :
This problem also occurs using Java Web Start 1.0.1_02.

A DESCRIPTION OF THE PROBLEM :
The initial use of an application works fine with Web
Start, but updating one of the application's JAR files
causes Web Start to hang upon the next use of the updated
application.

Here are the details: The updated JAR file is loaded and
validated by Web Start, however nothing happens after the
progress bar reports "Scanning entries (100% done)".
If Web Start's cancel button is clicked the application can
be relaunched run without further problems.

For testing purposes I updated the JAR file by resigning it
with jarsigner.
All of the application's JAR files were signed, however I
don't believe this is necessary to cause the problem.

This problem has been reported numerous times over the past
year. See the following URLs:
http://forum.java.sun.com/thread.jsp?forum=38&thread=168248
http://forum.java.sun.com/thread.jsp?forum=38&thread=286088

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Launch an application with Java Web Start.
2. Modify one of the application's JAR files in a way that
will cause Java Web Start to download it when the
application is next launched.
3. Launch the application with Java Web Start.

EXPECTED VERSUS ACTUAL BEHAVIOR :
I think Web Start should not hang.
It should launch the application
(I realize the updated version of the application may not
be used until the next launch, as per
http://java.sun.com/products/javawebstart/faq.html#14)

REPRODUCIBILITY :
This bug can be reproduced always.
