David Radley commented on ATLAS-2269:
-------------------------------------
The symptoms of the older versions of the models was that the new Jackson
libraries could not deserlialise the json in the model files. I saw this when
using
ObjectMapper mapper = new ObjectMapper()
.configure(DeserializationConfig.Feature.USE_BIG_DECIMAL_FOR_FLOATS, true);
to deserialise json.
then
AtlasTypesDef typedDef = mapper.readValue(file, AtlasTypesDef.class);
This threw exceptions.
I have not seen errors in runtime Atlas - because I cannot start Atlas due to
the current state of the code. I suspect that reading the json files may
produce errors. In my tests unrecoginised content was causing errors. The
unrecognised content highlighted mismatches between the json model files and
their equivalent Java classes.
I also corrected a spelling mistake in the models of the word translated.
If applications had been written and relied on the old model files then those
applications would need to be rewritten. As the models are very new and only in
master - I think this is a low risk; so changing the model files without
versioning them at this stage should be acceptable. If we get feedback such
that this approach is not acceptable we can make these changes in new versions
in patches.

> while playing with serializing the models, I notice that the latest Jackson
