ArrayIndexOutOfBoundsException while using undo

[Chris2011]

While testing my PR, I got this exception, when I changed a json file. I changed the code inside of it, hit save and did often a undo (ctrl + z) and after the second undo or smth like that, I got this exception, which shouldn't happen:

Anything new here?

[Chris2011]

Can please someone have a look who has more knowledge about it, than me? @bennyn can you maybe have a look please? Otherwise the plugin will be unusable.

[Chris2011]

Hey @emabrey do have time to have a look? Benny pointed me in your direction ;).

[emabrey]

I'm attending school currently and I have several exams this week, but if I have the time I'll try to look at this this week. Otherwise I'll do it as soon as I can, but I will look at this ASAP either way.

[Chris2011]

@emabrey no worries, we have some prio: high bugs/tickets which prevents some users of using this plugin. We should focus on those things first.

[Chris2011]

Thx for your interest and info :)

[Chris2011]

Hey @emabrey how is the progress here?
