My software has a rest call which returns a byte[], it is fairly simple
as:
Response.ok(data).type("application/octet-stream").build();
This was working fine, until we upgraded from java 6 to java 7. Now I get
an internal error. Getting some detailed logging information I see the
below in the log.
It suggests that wink does not have a writer that can work out what to do
with a byte[]. Does anyone know if something changed between java 6 and 7
which might mean I have to explicitly tell wink how to write a byte array?
I would assume there is some way to register this manually, but I can't
find it for wink...
