That's why I am asking, cause if all files for all tests will be just in 
a jni folder, it will be a real mess.
That's why I do not understand why we can not group files in folder with 
a bug number as a name underneath "jni" folder to operate faster between 
the folders, otherwise developers must use some guideline on how to name 
the folders of their bugs.
