SWTBot typeText is getting a java.lang.ExceptionInitializerError [message #528194]

I am trying to use SWTBot on my laptop which has F-12 installed. I am running a test which runs fine on my F-12 desktop with SWTBot, but it fails in trying to do the SWTBotText.typeText() method with the exception above in org.eclipse.swtbot.swt.finder.keyboard.Keyboard.typeText.

Why is this happening? The release of SWTBot on my laptop is later than the one on the desktop (2.0.0.536-dev-e35 vs 2.0.0.512-dev-e35). Both are x86 platforms.

Hi Jeff,

Could you provide a stack trace so we can figure out where and why it is
happening ?

Appears not to like EN_CA keyboard layout. My keyboard preferences show USA and I also did a setxkbmap us which doesn't help.

Are you sure that SWTBotPreferences#KEYBOARD_LAYOUT is set to EN_US?

It is not . The value of SWTBotPreferences.KEYBOARD_LAYOUT gets set to EN_CA which matches I guess my LANG env variable setting??. Manually setting the field to :"EN_US" in my @BeforeClass method fixes the problem but this seems rather hokey.

Is there a better way to set this up and why doesn't the code simply default to "EN_US" if such an error occurs?

SWTBot tries to guess your keyboard layout based on your env language.
This would work really well if it wasn't for bug 280562 and bug 280824.
I have to do the same fix in a @BeforeClass method. You could also
define the java property (you know, -Dname=value)
org.eclipse.swtbot.keyboard.layout to EN_US to remove the need of a
@BeforeClass, but I prefer the @BeforeClass because it's a workaround
for those two bugs.

Defaulting to EN_US might sound like a good idea, except that you'll get
weird behavior while you type text if your native keyboard layout isn't
EN_US. And this would be way more complicated to debug than to fail
early with an exception.

Hope this helps.

http://wiki.eclipse.org/SWTBot/Keyboard_Layouts might be helpful.
