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

Managed to reproduce the problem. Setting a String to the response does work, but a byte[] makes it blow up:

Works: 
{code}
return Response.ok("byte array forever").build();
{code}

Fails with the Exception as above:
{code}
return Response.ok("byte array forever".getBytes()).build();
{code}

> Currently Meecrowave tries to serve too much mime types via Johnzon. This leads to ugly NullPointerExceptions.
> Given the following REST endpoints:
> {code:java}
>     @GET
>     @Path("test4")
>     @Produces(MediaType.APPLICATION_OCTET_STREAM)
>     public Response testOctetStream() { ...}
> {code}
> or 
> {code:java}
>     @GET
>     @Path("test5")
>     @Produces(MediaType.APPLICATION_OCTET_STREAM)
>     public byte[] testOctetStream() { ...}
> {code}
> We currently blow up with a NPE:
> {noformat}
> Caused by: java.lang.ClassCastException: [B cannot be cast to [Ljava.lang.Object;
