I have created a trivial JAXB Provider:
@Provider
@Consumes(MediaType.APPLICATION_XML)
@Produces(MediaType.APPLICATION_XML)
public class TrivialJaxbProvider implements MessageBodyReader<Object> {
@Override
public boolean isReadable(Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return true;
}
@Override
public Object readFrom(Class<Object> type, Type genericType,
Annotation[] annotations, MediaType mediaType, MultivaluedMap<String,
String> httpHeaders,
InputStream entityStream) throws IOException,
WebApplicationException {
try {
return
JAXBContext.newInstance(type).createUnmarshaller().unmarshal(entityStream);
} catch (JAXBException e) {
throw new WebApplicationException(e);
}
}
}
and used it for this test. It worked fine with 750 threads.
So it seems that the bug is in a JAXB Provider.
I'll try to find some time to look into it. Anyway, meanwhile you can use
your own JAXB provider and it should work.
