> Referring to this thread: http://openejb.979440.n4.nabble.com/Possible-JSON-bug-in-TomEE-1-5-and-1-5-1-td4658328.html
it appears that the default setting of serializeAsArray is set to true for the standard CXF
JSONParser.
> This appears to lead to the situation where even the root-objet of the marshaled object
tree is formatted as an array. The CXF Unmarshaler (not sure which class is doing this exactly)
fails if root object is formatted as an array (I have experienced this error in the case where
my root object was NOT a collection).
> Example:
> class MyObject {
>  String id;
> }
> is marshaled as (square braces '[' indicate an array):
> {"myobjectinstance:[{"id":"12345}]}
> and the webmethod "receiving" the MyObject that is formatted with the square braces will
fail:
> @Consumes("application/json")
> @POST
> @Path("/process")
> public MyObject process(MyObject myObjectInstance) {
> ...
> }
> So solution could be
> - to set serializeAsArray to false or
> - somehow in other way ensure that single instances in json are formatted as such,
> - or make standard CXF json unmarshaler more tolerant with single instances formatted
as an array.
