I reproduced this bug with build 1.4.1-beta-b12.

I want to transfer an object wrapped in a transferable with
DataFlavor.javaJVMLocalObjectMimeType data flavor
via Windows system clipboard within the same JVM.
In javadoc for DataFlavor.javaJVMLocalObjectMimeType there
are no specified constraints on a locally transferring object
with this data flavor.
But NotSerializableExeption is thrown when contents of
system clipboard are set and following test case demonstrates it.

---------- BEGIN SOURCE ----------
import java.awt.datatransfer.*;
import java.awt.*;
import java.io.*;


class NotSerializableLocalTransferable implements Transferable {
    public final DataFlavor flavor;

    private final DataFlavor[] flavors;

    private final Object data;


    public NotSerializableLocalTransferable(Object data) throws Exception {
        this.data = data;
        flavor = new DataFlavor(
            DataFlavor.javaJVMLocalObjectMimeType +
            ";class=" + "\"" + data.getClass().getName() + "\"");
        this.flavors = new DataFlavor[] { flavor };
    }

    public DataFlavor[] getTransferDataFlavors() {
        return (DataFlavor[])flavors.clone();
    }

    public boolean isDataFlavorSupported(DataFlavor flavor) {
        return this.flavor.equals(flavor);
    }

    public Object getTransferData(DataFlavor flavor)
        throws UnsupportedFlavorException
    {
        if (this.flavor.equals(flavor)) {
            return (Object)data;
        }
        throw new UnsupportedFlavorException(flavor);
    }


    public static void main (String [] args) throws Exception {
        NotSerializableLocalTransferable t = new NotSerializableLocalTransferable(new NotSer());
        Toolkit.getDefaultToolkit().getSystemClipboard().setContents(t, null);
    }
}


class NotSer implements Serializable {
    private Object field = new Object(); // not serializable field
}
---------- END SOURCE ----------

Here is the output of the given test case.
