Hi Chris,
In some case of mine, the path I took is I used a ThreadLocal based
storage to store Http* classes from a Jersey resource to be used from
classes needing them but not being able to avail them through DI.
Reading through your contents I would have done some thing similar
with the logic residing in DateAdapter.
Regards,
Imran
