LTP: XMLEncoder could not write object of type java.awt.Insets (fails since mustang-b76)

JCK : JCK6.0 b20
J2SE : FAIL - *SINCE* mustang b76
Platform[s] : FAIL - seems to be all
switch/Mode : FAIL - default
Regression : Since tiger

This test fails because b76 unable to run the following code (part of the test api/java_beans/XMLDecoder/index.html#read[XMLDecoder0034] ):

import java.beans.*;
import java.io.*;
import java.awt.*;

public class Bean{

public static void main(String args[]){

        XMLEncoder xmlEnc = new XMLEncoder(new ByteArrayOutputStream());
        xmlEnc.writeObject(new java.awt.Insets(1, 2, 3, 4));
}
}

then this code is run it displays at console the following message *without any exception*:

java.lang.NoSuchMethodException: java.awt.Insets.getTop()
Continuing ...
java.lang.NoSuchMethodException: java.awt.Insets.getLeft()
Continuing ...
java.lang.NoSuchMethodException: java.awt.Insets.getBottom()
Continuing ...
java.lang.NoSuchMethodException: java.awt.Insets.getRight()
Continuing ...
java.lang.IllegalArgumentException
Continuing ...
java.lang.Exception: XMLEncoder: discarding statement XMLEncoder.writeObject(Ins
ets);
Continuing ...

and then everything goes wrong for api/java_beans/XMLDecoder/index.html#read[XMLDecoder0034]
