Description Robert Marcano 2008-06-23 19:57:46 UTC
Description of problem:
The pack() method of the Window class allow to resize the window based on the
contents preferred sizes, when using OpenJDK on the following example, the
window always have a empty area below (that does not happens of the Sun Java

  JFrame frame = new JFrame();
  JPanel panel = new JPanel(new FlowLayout());
  panel.add(new JButton("Testing..."));

Version-Release number of selected component (if applicable):

See attached test case, and comparison screen shots

Additional info:
the font selection looks different too, but I think that is related to the
better font selection than the SUN Java do when using the GTK Look and Feel.

See the empty are below. It happens using compiz and metacity, so it does not
looks like a Window Manager related problem at first sight

I confirmed this and reported it upstream to Sun.

Comment 6 Lillian Angel 2008-07-15 15:40:02 UTC
Sun says this is not a bug, and intentional. Closing

Bug demostration

I am sorry but this is a bad review from Sun, the new attached image shows the
minimum size of a window on Windows, and a the JFrame shown on Linux with the
problem, as you noticed the smallest window size has nothing to do with the bad
pack() behaviour. I will be adding comments to the Sun bug, please reopen this
in order to keep track of it
