Stefan Miklosovic commented on CASSANDRA-16855:
-----------------------------------------------
There are classes in o.a.c.cql3.Json which are related just to CQL. I left them
there and I moved everything else to o.a.c.utils.JsonUtils. So the state we
find ourselves in is:
1) o.a.c.cql3.Json is used just in that package (or subpackages) and nowhere
else. I can not make that class package protected because it is also used in
o.a.c.cql3.selection.Selection
2) I moved all other stuff from o.a.c.cql3.Json to o.a.c.utils.JsonUtils
3) I moved all JSON related code in FBUtilities to o.a.c.utils.JsonUtils
This means that all other code which needs to interact with JSON goes to
o.a.c.utils.JsonUtils only, FBUtilities are a lightweight a bit and Json stuff
in cql3 package is not spilling over.

> Jackson library is used for most JSON reading/writing, but there are couple
> of places where older "json-simple" library is used, mostly for diagnostics
> output. Replacing those minor usages would allow removal of a dependency, one
> for which the last release was made in 2012.
> Places where json-simple is used are:
> * src/java/org/apache/cassandra/db/ColumnFamilyStore.java
> * src/java/org/apache/cassandra/db/commitlog/CommitLogDescriptor.java
> * src/java/org/apache/cassandra/hints/HintsDescriptor.java
> * src/java/org/apache/cassandra/tools/nodetool/stats/StatsPrinter.java
> (and some matching usage in couple of test classes)
> I can take a stab at replacing these uses; it also looks like test coverage
> may be spotty for some (StatsPrinter json/yaml part has no tests for example).
> It is probably best to target this for "trunk" (4.1?).
