List problem in MappedXMLStreamWriter

[sberyozkin]

List results = new ArrayList();
results.add("aaa");
results.add(1L);
results.add("bbb");
results.add(2L);

expected result:
{"result":{"list":[
{"string":"aaa","long":1,"string":"bbb","long":2}

]}}
but actual:
{"result":{"list":[
{"string":["aaa","bbb"],"long":[1,2]}

]}}

Jettison seems to auto-merge the elements with same type, which saves space, but is incorrect behaviour. The order of a list is important and needs to be kept.
