I agree with you J8 is not necessary and Im not using it for now Sadly, fixes and unrelated changes are mixed in the commits and GitHub doesn't provide a mechanism to make selective pull request, maybe we can use a feature branch next time. Can I create the pull request with all my changes? Regards

Yes, please Mainly for educational reasons, I would like to apply Java 8/9 at some point and there is no better way to learn than programming. I think this project is perfect for my purposes, not so big not so small. Checking the code I found some errors and I think it is better to fix them than to change the version. Also, I would like to integrate these changes into Freemind, in which I've been working from time to time

Small fixes, performance improvements and general clean code
