the instance field name in T2KFontFile, to the best of my knowledge, is not used. I believe it (and all related code) could be removed.

If we decided to keep this field, we should fix the constructor:
    private T2KFontFile(String name, String filename, int fIndex)
                                                    throws Exception {
        this.name = name;
        this.filename = filename;
        init(fIndex);
        if (name == null || name.equals("")) {
            name = fullName;
            if (name == null) {
                name = "";
            }
        }
    }

note that the final 5 lines in this code is adjusting the parameter name, not the instance field (this.name).
