Masatake Iwasaki commented on HTRACE-148:
-----------------------------------------
I can still reproduce this issue. Jackson seems to fail to get deserializer
specified by annotation in MilliSpan.java.
{noformat}
SEVERE: Got exception
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized
field "s" (class org.apache.htrace.impl.MilliSpan), not marked as ignorable (7
known properties: "traceId", "timelineAnnotations", "spanId", "parents",
"kvannotations", "processId", "description"])

Adding deserializer explicitly in TestHTracedRESTReceiver resulted in
compilation error.
{code}
ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addDeserializer(MilliSpan.class, new
MilliSpan.MilliSpanDeserializer());
mapper.registerModule(module);
{code}
