> The flush() method in XMLEncoder doesn't take into account the fact that data may have already been written. Consequently, calling XMLEncoder.flush() may result in the same data being written twice.
> Here's a testcase:
> import java.beans.XMLEncoder;
> import java.io.ByteArrayOutputStream;
> public class Bugzilla125927 {
>     public static void main (String args[]) {
> 	Object object = "hello";
> 	byte[] out = null;
> 	ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
> 	XMLEncoder encoder = new XMLEncoder(outputStream);
> 	try{
> 	    encoder.writeObject(object);
> 	    encoder.flush();
> 	    encoder.close();
> 	    outputStream.close();
> 	}
> 	catch (Exception ex) { 
> 	    ex.printStackTrace();
> 	}
> 	System.out.println(new String(outputStream.toByteArray()));
>     }
> }
> On the Sun JDK, this results in the following output:
> <?xml version="1.0" encoding="UTF-8"?>
> <java version="1.5.0_04" class="java.beans.XMLDecoder">
>  <string>hello</string>
> </java>
> On Harmony, you get the following:
