java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Server VM (build 1.6.0_01-b06, mixed mode)


ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
Using a splash screen on an application that installs a tray icon crashes the JVM.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile application into a jar using the ant build.xml. Execute the jar. Using the -splash java command line option with the file 'ind_sm.png' will prevent the crash. Or, change the build.xml to use ind_sm.png instead of DukeWithHelmet-64.png as the splash screen will also avoid the crash. Different splash images may work on Java 1.6.0 but not work on 1.6.0_01.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Splash screen display, icon installed in system tray.
ACTUAL -
Splash screen displays, then JVM crashes in call to SystemTray.add(TrayIcon)

ERROR MESSAGES/STACK TRACES THAT OCCUR :
see hs_err.log in attachment


REPRODUCIBILITY :
This bug can be reproduced always.
