I had another look at this today and it seems that if you add a Calendar for 
the validFrom and validUntil. The error is thrown.

Do I have to configure the Calendar object in a specific way?

I have solved the problem by converting the calendar object to a http date.

I added the following code after 'sirc.prepareQueryParams(params);' in Jec2 
class in the method 'requestSpotInstances'. 

if (sirc.getValidFrom() != null) {
   String newDate = httpDate(sirc.getValidFrom());
   params.put("ValidFrom", newDate);
}
if (sirc.getValidUntil() != null) {
   String newDate = httpDate(sirc.getValidUntil());
   params.put("ValidUntil", newDate);
}

I hope this helps.
