FULL PRODUCT VERSION :
java version "1.4.0-beta3"

Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.0-beta3-b84)

Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed
mode)


FULL OPERATING SYSTEM VERSION :
Windows Millennium [Version 4.90.3000]



A DESCRIPTION OF THE PROBLEM :
Typing a letter while a JTree or JList has focus now
makes the selection jump to the first/next node/item
whose text starts with that letter. While this is a
nice feature, in its current form it interferes with
other features such as menu mnemonics (see steps
to reproduce).

  Suggested fix:
Only enable JTree/JList letter navigation when the user
doesn't press any modifier keys such as ALT or CTRL.


REGRESSION. Last worked in version 1.3.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
TestCase1 displays a JTree
    Click on the first node then type ALT+F
      (Note: sometimes it's necessary to do this twice
       before the effect can be seen)
    The File menu will be opened
      - OK
    The selection will change to 'food'
      - not OK since the user only intended to open the
File menu

TestCase2 displays a JList
    Click on the first item then type ALT+F
      (Note: sometimes it's necessary to do this twice
       before the effect can be seen)
    The File menu will be opened
      - OK
    The selection will change to 'freak'
      - not OK since the user only intended to open the
File menu

This bug can be reproduced always.
