	This is ~~really weird~~ because ~~we've~~ a ~~stock~~ ~~ICS~~ ~~and~~ ~~the~~ bouncycastle is ~~working~~ ~~when~~ ~~called from~~ the ~~apk~~ so ~~what??~~		This is because there is an extra dependency for bouncycastle, here is how to get the deps in a very hacky way:
			$ adb shell strings /system/framework/bouncycastle.odex\|grep odex
			/system/framework/core.odex
			/system/framework/core-junit.odex
			So the proper way to call our jar is now:
			<source lang=bash>
			$ANDROID_HOME/platform-tools/adb -d shell \
			/system/bin/dalvikvm -Xbootclasspath:/system/framework/core.jar:/system/framework/core-junit.jar:/system/framework/bouncycastle.jar -classpath /sdcard/CmdLine.jar $PACKAGE.HelloWorld
