That's a shame. I'll have to pass on it until the Java requirement is removed completely. I'm ok with an entirely custom self-contained version of Java Runtime being included with the game itself (like what MineCraft has done) but I refuse to do any installs of the JRE to my actual computer. JRE has been insecure and a major security risk for the end-user for well over a decade now. Just like Flash, Java (and the JRE) is just a relic of the past that needs to remain there for good.
HTML5 and JavaScript are the future. Time to update ;)
