Thank you. Please use git rebase to update your branch and remove the merge commit.

May I ask if your contribution is part of a uni or school class? (I am collecting information on and comparing various software engineering courses that encourage OSS development as part of their curriculum for research purposes)

[unleashedme]

@TobiGr git rebase is done.
No, this contribution is not a part of any uni or school class. I was just trying to start some Open Source Contributions.

Thank you, please change the exception message of the ParsingExceptions to something more useful than the one of the exception you're wrapping and it will be merged :)

@AudricV changes done.
Do i need to squash these multiple commits??

[AudricV]

@unleashedme Not in this case, we can do this in the merge :)
