java.lang.NoClassDeffoundError when attempting to use FileFilter

Question

My application works on my laptop, but when I attempt to run the app that uses the code for FileFilter I get the NoClassDeffoundError on a production machine. my version is 1.8.0.201 and the prod machine is 1.8.0.121.

FileFilter dirFilter = new FileFilter() {
    @Override
    public boolean accept(File file) {
        if (file.isDirectory()) {
            return true;
        } else {
            return false;   
        }
    }
};
