     * typing this, Java 8 is some 4 months away, and there are still people who use my
     * code who are running Java 6. Like 5% of the users are using an obsolete version
     * of Java from 2006. It's not like it's even that hard to update. Honestly, you
     * just click a couple of buttons, check a box, and bam, you've made my job easier.
     * And yet, because these people are so lazy, I'm forced to compile with Java 6 to
     * accommodate for this ridiculous minority. I say this because I could accomplish
     * what this try-block does in about 2 lines of code, but nope, gotta use Java 6.
     * I'm really psyched for lambda expressions in Java 8, but I can't even use those
     * until Java 9 is out, because there'll be those morons who just refuse to update
     * past 7. It's stupid, it really is.</rant>
