Hi Dmitry! You really should make more of a song-and-dance about these features like free Pro licenses and small biz discounts!
I thought I was doing good job there - there was a prominent "Get It Free" link on all Excelsior JET pages prior to this charity program, and there is a block of links to the various discounts options right on the order page. Even in the charity program FAQ there are multiple links. What else do you think I could do here?
Slimdown seems like a much more sensible tradeoff in space for complexity and reliability.
We expected that Project Jigsaw would make it even more sensible, but that has been pushed to Java 9...
It used to be the #1 feature request, but now Java 7 support seems to be taking over.
