Hi Tim,
Can you try the latest, 1.0-ea-SNAPSHOT, and see if you get the same
behaviour. I tried using the latest and i cannot reproduce it.
BTW not sure if you are aware: Jersey does not have built in support
for the conversion of an instance of Number to a sequence of bytes. If
you have not already done so, you will need to add a message body
writer for instances of Number.
Paul.
