I uploaded a synchronized version. The main problem is that the same functionality is written in Jacoco project under LGPL which couldn't be imported. I wrote my own version from scratch, and this mistake clearly proves that it's independent, as I added my own mistakes ;-) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
