java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b65)
Java HotSpot(TM) Client VM (build 1.4.0-beta-b65, mixed mode)


Calling Window.setSize moves a Frame's window, sometimes off the
screen.

(I had a detailed bug report, but Netscape trashed it. I'll try to re-compose
for as long as I can stand.)

My environment is:
- JDK 1.4.0 beta, for Linux
- Linux distribution: Debian potato, pretty vanilla
- X11 environment: xfree86 3.3.6, color depth 15 (configuration attached
  below)
- window manager: FVWM 2.2.4 (configuration attached below)

My test program creates a java.awt.Frame, sets it size, and sets it
visible. After a delay, it sets a larger size. After another delay,
is calls setVisible(true) again.

When it sets the larger size, the window moves up and to the left,
usually moving off the screen.

In a little more detail:
- When the window first appears, it briefly pops up somewhere in the
  middle of the screen (per my window manager's placement algorithm),
  and then moves to the upper left corner. (Separately, is that
  intended, a configuration problem, or a long-extant bug (1.3.something
  does that too)?)

- When the program calls setSize, the window moves up and to the left,
  sometimes completely disappearing, sometimes leaving its lower right
  corner showing in the upper left of the display. If I switch to
  a virtual desktop that is down and to the right, I can see that the
  window has moved up and to the left and onto another virtual desktop.

- When the program calls setVisible(true) again, the window reappears
  on the screen in a new location (apparently subject to the window
  manager's placement algorithm as if it were a new window).

- The size of the reappeared window varies:

  - At first, I didn't notice a problem, so the size was probably right.

  - On later runs (with apparent reason for changing), the window had
    zero height but enough width for the normal window manager
    decoration (the title bar and some buttons).

  - No, the window has zero height. (The window manager decoration
    consists of only the border; no title bar or buttons appears.)

Appended are:
1: my test program
2: my customizations to Debian's default FVWM configuration
3: my XF86Config file
