stackOverflow on serialize org.apache.commons.lang3.tuple.Pair

See original GitHub issue

ObjectMapper objectMapper = new ObjectMapper();
        try {
            JsonGenerator generator = objectMapper.getFactory().createGenerator(System.out);
            Pair<Integer, String> a = Pair.of(10, "100");
            objectMapper.writer().writeValue(generator, a);
        } catch (Exception e) {
            e.printStackTrace();
        }

will produce stack overflow:

@ChinaXing Jackson 2.7 has a completely rewritten type resolution system, and I was asking because problems previous versions had can not be fixed for those versions in patches. There were a few known issues and this could be one of those.

I would suggest you to see whether things work with 2.7.3; I would expect that to handle recursion better.
