I downloaded it for testing purposes only, I am no beginner in Bitcoin and I use Electrum plus Ledger HW.1 hardware wallet. However I see you have programmed it in Java , not a good thing knowing how many vulnerabilities there are in this system (Silk Road user were shut down together with the website because of an exploit in Java) . I am keeping it for a few days to an indefinite amount of time in my work PC to test with small bitcoin amounts.
This is what comes up when I try to install it.
Never mind, it worked now. Let's see how it will progress, don't trust Java much I told you before but lets try.
