Hi @jan-zajic,

We have to wait for @rhyolight (Matt Taylor) to approve your License form.

@rhyolight can you have a look when you get a chance?

[rhyolight]

Sorry I missed this. Will do next business day.

I think this is ok to merge now.

Hi @jan-zajic,

I apologize for the delay in getting back to this PR, are you still around? Let me know because I have some changes I would like to make before this PR is merged.

Cheers,
David

Hi @cogmission, i was a little busy but i'am back, what changes do you mean?

[jan-zajic]

@cogmission, are you still around? I am. Or is htm.java dead (Latest commit on 14 Sep 2017)?

@jan-zajic I'm still here... Been real busy w/my day job which also used to allot time for HTM.Java development (since they are also sponsors), but my role has expanded and left less time for HTM.Java recently. I will be getting back very soon though because I have projects that require it.
