iCalendar allows for the addition of new properties and parameters if you 
look at the syntax you will see "iana-token" items used as a place holder 
for future standard protocol elements). The EMAIL parameter is defined in a 
draft specification which the IETF is working on: 

ical4j should not be so strict as to refuse to accept new standard 
properties. As you can see in that draft, there are a whole bunch of new 
ones being worked on.

That said, please check to see if you have the latest version of ical4j, 
because it may already support the new protocol elements, or provide a more 
relaxed mode so that it does not fail when something new comes along that 
it does not recognize.
