Code:

public class FIleNameFormatException extends Exception {

    private static final long serialVersionUID = 1L;

    public FIleNameFormatException(Exception e) {
        super(e);
    }
}

Detected: no warning on class name.

Expected: warring on class name. Please create UT for this.

[romani]

Reported problem is valid case, to cover this we need to make allowedAbbreviationLength=0.
extend ignore list to have "IT" and "I" to suppress most false-positives.
but in this case we have problem on following cases, when capital letter is a last. Message is "Abbreviation As Word In Name: Abbreviation in name must contain no more than '0' capital letters."

            double scaleX = getWidth() / (double) backgroundImage.getWidth(null);
            double scaleY = getHeight() / (double) backgroundImage.getHeight(null);

so please fix this problem.

So, it shouldn't display warning on scaleX and should display warning on FIleNameFormatException when allowedAbbreviationLength=0. Right?

[romani]

right.
