Come da titolo , dopo aver aggiunto nella mia applicazione
codice:
try { UIManager.setLookAndFeel("com.oyoaha.swing.plaf.oyoaha.OyoahaLookAndFeel"); }
 catch (Exception e) { e.printStackTrace(); }
durante la fase di compilazione Eclipse mi segna come errata l'inizializzazione dei miei fileChooser (solo durante la compilazione) piantando di fatto l'applicazione.
Ovviamente il problema sta nel LookAndFeel ma mi chiedevo se si potesse ovviare al problema in qualche modo

grazie.
