Jean Marc updated AXIS2-5044:
-----------------------------
Description:
When Mapped convention is used, JSONMessageFormatter creates an XMLStreamWriter
from Jettison library of type MappedXMLStreamWriter
and executes the following code
XMLStreamWriter jsonWriter = getJSONWriter(bytesOut);
element.serializeAndConsume(jsonWriter);
jsonWriter.writeEndDocument();
at 3 places in the class (in getBytes(), getTargetAddress() and writeTo() ).
In the above code, there is no call to jsonWriter.writeStartDocument().
This works for Jettison library v1.1 and below because it does not follow the
SAX event flow, but Jettison v1.2 and above have been refactored to respect the
SAX event chain,
and the XMLStreamWriter expects the calling serializer to generate a
startDocument() event at the beginning.
Actually, the axis-json lib 1.5.4 does not specify a Maven version dependency
on Jettison so any version should do, but with Jettison v1.2+
a simple client trying to serialize a OMElement to send a soap message triggers
a NPE in Jettison when the last endElement() event is triggered
because the call to startDocument has never been made.
Simple solution is to add jsonWriter.writeStartDocument() before calling
element.serializeAndConsume().
Remaining Estimate: 5m
Original Estimate: 5m
