#1256 PositionLiteralsFirstInComparisons false positive with Characters

[Daniel Gredler]

The following class triggers a PositionLiteralsFirstInComparisons violation:

public class LiteralTest {

    protected final boolean check;

    public LiteralTest(Character c) {
        check = c.equals('x');
    }

}

There are two issues with this:

1. One can't just switch the variables and write 'x'.equals(c)

2. The error message ("Position literals first in String comparisons") seems to imply that this should be checking only String literals -- not char literals.
