      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.
