On Mac OS X with Java 6 32-bit JVM - Browser fails to load
http://screencast.com/t/iYnsp7ekB1Ha

Steps to reproduce:

1. You need to have Java 6 and Java 7 installed on your Mac
2. Install a 32-bit version of Eclipse and run it with Java 6
3. Go to Preferences > Java > Installed JREs and remove all JREs except Java 7
4. Try to run BrowserSim

Actual result:
BrowserSim does not start. No messages shown.

Update:
This happens because Oracle Java 7 does not support the 32-bit mode, so it cannot run 32-bit SWT libraries, which are used by BrowserSim.

Update 2 (reopening):
On step #1 you need to have Java 5 installed. This will lead to NPE when opening BrowserSim preferences

Workaround (if Java 7 installed):

1. Add (do not remove) Java 6 from Preferences > Java > Installed JREs
2. Go to Preferences > JBoss Tools > BrowserSim/CordovaSim and select Java 6 to run BrowserSim

Workaround (if Java 5 installed):
Remove Java 5 from the list of installed JREs
