FULL PRODUCT VERSION :
On windows machines:
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
On redhat machine:
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build Blackdown-1.4.1-01)
Java HotSpot(TM) Client VM (build Blackdown-1.4.1-01, mixed mode)
FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]
ADDITIONAL OPERATING SYSTEMS :
Microsoft Windows XP [Version 5.1.2600]
Windows 98 [Version 4.10.2222]
RedHat Linux 8.0, 2.4.18-24.8.0
EXTRA RELEVANT SYSTEM CONFIGURATION :
On the RedHat machine it is reproducible with Blackdown's
1.4.1 release. This probably means it happens with Sun's
release as well although I only tested with Sun's release on
Windows.
A DESCRIPTION OF THE PROBLEM :
When running code that loads a JPEG from a signed jar file
the application will just quit. It does not happen if the
file is a GIF or if it is a JPEG and the jar is unsigned.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Go to http://hera.csci.unt.edu/software/test/
2. Select the test.jnlp file. The jar file test.jar is
unsigned. Both buttons (Crash and Works) will work properly
and show the dialogs with the image.
3. Now select the test2.jnlp file. This jar file test2.jar
is signed. If you click on the Works button you will get a
dialog with the gif image. If you click on the Crash button
the program will crash.
The source code and images are all there if you need to
manipulate the test.
EXPECTED VERSUS ACTUAL BEHAVIOR :
It should have loaded the JPEG image and shown the dialog
normally whether signed or unsigned.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
An unexpected exception has been detected in native code outside the VM.

CUSTOMER WORKAROUND :
Use GIF and possible PNG (I have not tested this) instead of
JPEG. Or you could just use unsigned jars.
