@andreybleme great, please go ahead.

@andreybleme are you still working on this?

@iluwatar Hi, I would like to take this up, if no one else is already on it.

[iluwatar]

Yes, it seems @andreybleme is not active so you can take this.

@iluwatar Thanks. The blocker issues can be seen here.
Just submitted the PR. It fixes 6 of the 7 issues. The seventh seems to be by design. Please have a look and let me know.
