MultiPlex Look & Feel

[JFM]

Hi,

I have a problem with the so called MultiPlex L&F. With that technique one can implement
an "auxiliary" L&F which enhances the standard L&Fs.
I first describe you what I did and my problem afterwards.
I've written my own L&F:


//FileChooserLookAndFeel.java
public class FileChooserLookAndFeel extends LookAndFeel {
public UIDefaults getDefaults() {
UIDefaults table = new FileChooserUIDefaults();
Object[] uiDefaults = {
"FileChooserUI", "MultiSelectionFileChooserUI"
};
table.putDefaults(uiDefaults);
return table;
}

...
}


class FileChooserUIDefaults extends UIDefaults {
protected void getUIError(String msg) {
//do nothing
}
}




I've implemented a FileChooserUI:


//MultiSelectionFileChooserUI .java
public class MultiSelectionFileChooserUI extends FileChooserUI {
...
public void installUI(JComponent c) {
...
}
}




and to let Swing know that there is a new L&F, I called:


UIManager.addAuxiliaryLookAndFeel(new FileChooserLookAndFeel());




This works pretty good. The new UI does what it should do.
The problem is, that Swing prints a lot of error messages to StdErr:
java.lang.reflect.InvocationTargetException
Multiplexing LAF: createUI() failed for javax.swing.JPanel ...
Multiplexing LAF: createUI() failed for javax.swing.JScrollPane ...
...

One message for each Component which is used in my app. I think, the MultiLookAndFeel class writes these messages out.
There are no entries in my own UIDefaults for all these components. But I don't want to enhance them all - just the FileChooser.

Is there a way to suppress these messages ?

Thanks, Jan.
