[Bug awt/26450] New: First few repaints of lightweight Component fail to paint

[sgilbertson at gcc dot gnu dot org]

Running LightweightRepaintTest.java, the first couple of repaints don't happen.
 The program puts up a frame with three fields in it.  With the Sun JRE, you
see:
  "--" "--" "--" when the frame first appears
  "Pass 1" "--" "--" one second later (field 1 yellow)
  "Pass1" "Pass 2" "--" another second later (field 2 yellow) and so on

Same thing on GCJ/XLIB with the GLightweightPeer.repaint and Graphics.hitClip
patches.  I don't have a GCJ/GTK build handy, so I don't know what it does.

With JamVM 1.4.2 + Classpath (from CVS 2006-02-23), the first two paints don't
happen, so you get a solid gray box for two seconds at startup, followed by
"Pass 1" "Pass 2" "--" and so on.

Classpath configured with: --with-jikes --enable-jni
Obtained from CVS just after this patch:
http://developer.classpath.org/pipermail/classpath-patches/2006-February/000623.html
(the test program didn't paint at all without that patch, except when you
re-sized the frame)
