Classe Icone - Refatorar metodo createImageIcon

Criado classe Icone.java com duas assinaturas do método createImageIcon(...) .
Refatorar todos icones:

TelaPrincipal

TelaUsuario
- createImageIcon(..)

TelaCiente
- createImageIcon(..)

TelaOS

setIcon(new javax.swing.ImageIcon(getClass().getResource java.lang.NullPointerException

lblStatus.setIcon(new javax.swing.ImageIcon( "Z:\\java\\javaMySQL03_infoX\\src\\main\\java\\br\\com\\infox\\icones\\dbok.png"));

Is OK!

But this:

lblStatus.setIcon(new javax.swing.ImageIcon( getClass().getResource("/br/com/infox/icones/dbok.png")));

make ERROR:

My project is running with Maven

In https://stackoverflow.com/questions/14593766/getclass-getresource-exception
I used this tip :
System.out.println(getClass().getProtectionDomain().getCodeSource().getLocation());
And the print was:
file:/Z:/java/javaMySQL03_infoX/target/classes/
