Java/activeweb Jackson and non-Jackson implementation

[zloster]

This framework has two modes: default and Jackson. https://github.com/zloster/FrameworkBenchmarks/blob/master/frameworks/Java/activeweb/benchmark_config.json
But the JSON controller source suggests that only JSON test has different implementation. Note that Jackson is instantiated in the controller and used explicitly in the method.
This needs investigation/corrections.
Each controller have to entry points (see benchmark_config.json): one is returning the data via template that produces JSON, the other is calling Jackson for the serialisation.
