It doesn't have anything to do with Websphere, as far as I can see. So I will close this copy of the question.
I note from their website that they describe their customer support as "WOW". So you would think you could ask them a question like this, instead of having to post it on an Internet forum. On the other hand when they devote their entire FAQ to explaining a court case they are involved in, perhaps they actually don't have any time for customer support.
