Description
XMLEncoder does not serialize a value of the property "accelerator" in JMenu and JMenuItem classes.
Comments
EVALUATION The property accelerator of the class JMenu is readonly. So we can support the property accelerator only in the class JMenuItem.

WORK AROUND Use the following persistence delegate: import java.awt.event.KeyEvent; import java.beans.Encoder; import java.beans.Expression; import java.beans.PersistenceDelegate; import javax.swing.KeyStroke; public class KeyStrokePersistenceDelegate extends PersistenceDelegate { protected boolean mutatesTo( Object oldInstance, Object newInstance ) { return oldInstance.equals( newInstance ); } protected Expression instantiate( Object oldInstance, Encoder out ) { KeyStroke key = ( KeyStroke )oldInstance; char ch = key.getKeyChar(); int code = key.getKeyCode(); int mask = key.getModifiers(); boolean onKeyRelease = key.isOnKeyRelease(); Object[] args = null; if ( ch == KeyEvent.CHAR_UNDEFINED ) { args = !onKeyRelease ? new Object[]{code, mask} : new Object[]{code, mask, onKeyRelease}; } else if ( code == KeyEvent.VK_UNDEFINED ) { if ( !onKeyRelease ) { args = ( mask == 0 ) ? new Object[]{ch} : new Object[]{ch, mask}; } else if ( mask == 0 ) { args = new Object[]{ch, onKeyRelease}; } } if ( args == null ) throw new IllegalStateException( "Unsupported KeyStroke: " + key ); return new Expression( key, KeyStroke.class, "getKeyStroke", args ); } }

EVALUATION It is necessary to create appropriate persistence delegate for KeyStroke and AWTKeyStroke classes. Also we should not mark the property "accelerator" as transient in MetaData.
