Hi,

I'm running into a problem with the Jersey-JSON serialization because I
need to satisfy an API which require me to serialize empty Collections.

The external party requires me to send JSON in the following format:

--------8<--------
{
  a : "Blabla",
  l : []
}
--------8<--------

but it looks like this is not possible to achieve with jersey because if
the l-attribute holds an empty list or null it is not part of the
serialized response:

--------8<--------
{
  a : "Blabla"
}
--------8<--------

Am I missing something obvious? What would you suggest to do instead?

Tom
