Uh ! Found stupid bugs while doing some code review:
1) classes were indexed by their name instead of their fullname...
It means that a class X in package Y could shadow class X in package Z. Great !
2) I was looking for duplicate not by the key but the value.
Obviouslly it could never work, fortunately due to
heavy memory usage, I did not used this method in XMLReport.
