THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
...
There's a plus and a minus for this - plus: we get better tested, better function (perhaps), better performance for some typical capabilities (e.g., parsing XML to/from Java Objects). Minus - it make the code depend on these other packages. Also, if it's working fine now, there's little motivation to invest in changing it.
Some areas to consider:
- XML parsing and writing for descriptors - use JAXB or Jackson (already used for JSON support)
