[Bug swing/34428] New: JSplitPane - wrong splitpane bar position

[thebohemian at gmx dot net]

In Processing (http://processing.org) a JSplitPane is used to split the code
editor (top) and an output window (bottom) from each other.

Everything is ok when the first application window opens: The splitpane bar
roughly centers between the editor and the output window.

However when you open the second window (e.g. through File/New) the bar of the
splitpane in the second window is moved completely to the top making the editor
invisible.

On the JDK the bar is always placed like in the first window.

I will add some screenshots to make the problem more understandable.

The JSplitPane is always initialized with this code:
splitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT,
                               upper, consolePanel);

    splitPane.setOneTouchExpandable(true);
    // repaint child panes while resizing
    splitPane.setContinuousLayout(true);
    // if window increases in size, give all of increase to
    // the textarea in the uppper pane
    splitPane.setResizeWeight(1D);

    // to fix ugliness.. normally macosx java 1.3 puts an
    // ugly white border around this object, so turn it off.
    splitPane.setBorder(null);

    // the default size on windows is too small and kinda ugly
    int dividerSize = Preferences.getInteger("editor.divider.size");
    if (dividerSize != 0) {
      splitPane.setDividerSize(dividerSize);
    }

    splitPane.setMinimumSize(new Dimension(600, 600));
    box.add(splitPane);

I had to disable some code that unconditionally sets a non-existing LnF on GNU
Classpath first:
