Description of the problem / feature request:

I'm unable to suppress InlineFormatString, neither by annotating the constant, nor by annotating the method that uses the constant.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

class Foo {

    @SuppressWarnings("InlineFormatString")
    private static final String FMT = "%s";

    @SuppressWarnings("InlineFormatString")
    String foo() {
        return String.format(FMT, "bar");
    }

}
