----------------------------------------------------------------

Ok another analysis, trinidad probably uses the system event, but that one =
is called outside of any real request (understandable since the destroy etc=
... is request independend) and getContentType then runs into this issue, u=
nfortunately.
One solution would be to delegate what is possible to the servlet context o=
bject
so that we at least can cover parts of the servlet functionality,

In this case getRequestContentType is questionable since we probably dont e=
ven have a request here since we still are in the init part of the system.
It would be interesting to see how the RI behaves in this case so that we h=
ave the same behavior here.. This is definitely one shady area of the sourc=
e where we should absolutely behave the same as the RI.
