fixed folder structure in order to get unittest running
* test folder: added java and resources subfolders
* moved tests to java subfolder
* moved resources to resources subfolder
* added dedicated test resource folder to pom.xml
* changed build.xml to use the correst test-source folder
* unittest run now via maven
Unittest fixed
* there is no 1-1 relation between a Json string and a JsonObject, so we compare the 2 toString outputs, they should be the same
