[Java] Errore sulle eccezzioni

[Fabietto206]

Devo ampliare un progetto svolto da un altro precedentemente, xò quando lo lancio mi genera le seguenti eccezioni:
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at gui.FrameMain.initComponents(FrameMain.java:325)
at gui.FrameMain.<init>(FrameMain.java:49)
at gui.FrameMain$51.run(FrameMain.java:1122)
at java.awt.event.InvocationEvent.dispatch(Unknown Source)
at java.awt.EventQueue.dispatchEvent(Unknown Source)
at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)
at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)
at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)

Qualcuno sa dirmi come evitarle??
