FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-
b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version
5.00.2195]

A DESCRIPTION OF THE PROBLEM :
I was using the XMLEncoder & XMLDecoder to save some graphical beans (a
JFrame with a few simple components added) and I noticed that while some
of the properties of the components were order-dependant, they were not
saved that way.

For example, if you use
JLabel.setDisplayedMnemonicIndex() before you use
JLabel.setText(), you get an ArrayIndexOutOfBoundsException.  The
XMLEncoder stores the properties willy-nilly and so when you retrieve
the object with a decoder, the displayedMnemonicIndex property gets
set before the text property and you get the exception.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.  Compile the sample code
2.  Run it.
3.  Observe the exceptions being
thrown

EXPECTED VERSUS ACTUAL BEHAVIOR :
I would expect that either one of two things:
1.  The beans would be able
to indicate dependant properties in some manner, and the XMLEncoder
would respect the dependancies.

or

2.  The beans specification
would state (maybe it does, I don't know) that properties must be
independant, and the swing beans would then implement their properties
in such a manner that you can set the displayedMnemonicIndex before you
set the text.

These are all approved for deferral to JDK 9 so you can update the FixVersion to state JDK 9. Kind regards, Mathias

WORK AROUND The XMLEncoder will use the the order or the property descriptor array that it retrieves from the Introspector. Since 1.4, this is now ordered by the name of the property. One workaround is to rename methods so that properties that must be exectued first should have property names that come sooner in the alphabet. ###@###.### 2003-04-07

EVALUATION This is similar in context to 4178930 and has been asked for by several high profile licencees and customers. We should commit this to Tiger. ###@###.### 2003-01-29 We may break this out as a seperate bug. A smaller version of the test case is: import java.beans.*; import javax.swing.JLabel; public class Test { public static void main(String[] args) { JLabel label = new JLabel("Test Text"); label.setDisplayedMnemonicIndex(0); ExceptionListener el = new ExceptionListener() { public void exceptionThrown(Exception e) { e.printStackTrace(); } }; XMLEncoder e = new XMLEncoder(System.out); e.setExceptionListener(el); e.writeObject(label); e.close(); } } It appears that the xml is written correctly however, when it is interpreted, the mnemmonicIndex property should be set after the text property. ###@###.### 2003-04-07 Unfortunately, the time for implementing features is over so this issue will have to be addressed in the next major release. ###@###.### 2003-10-17
