>             Project: Application Server 7
>          Issue Type: Bug
>          Components: EJB
>    Affects Versions: 7.1.3.Final (EAP), 7.2.0.Alpha1

> My ejb class contains this timeout method:
> {code:java}
>     @Schedule(dayOfWeek="Sun", persistent=false)
>     private void sunday(Timer t) {
>     }
> {code}
> When calling this timer.getNextTimeout(), it returned the Sunday after next Sunday (expecting next Sunday) when running on certain locales (it_IT, es_PE, etc).  It works as expected on other locales like en_US.  
> I added -Duser.language=it -Duser.country=IT to JAVA_OPTS when starting standalone server to use that locale.
> Seems to be a JDK bug.  There could be some differences how dates are calculated in different locales, but shouldn't be that big like skip one Sunday.  Today is Wed.
> One workaround is "to use locale.English when instantiating GregorianCalendar."  I tried it on 7.2 with it_IT, and got the expected Sunday.
