Piotr - Have you successfully used ProGuard with any Pivot apps?
If so, would you be able to share your experiences and any useful tips?
I'm sure it would be useful for others on the mailing lists.
There was a thread about ProGuard a few months ago, but it didn't get many
replies.

> Pivot displays ugly gray box sometimes before it loads the applet

> Key: PIVOT-754
> URL: https://issues.apache.org/jira/browse/PIVOT-754
> Project: Pivot
> Issue Type: Bug
> Components: wtk
> Affects Versions: 2.0
> Environment: Observed both on Linux and Windows Vista, Firefox 3.x
> and Firefox 4.0.1
> Java 6 update 25.
> Reporter: Piotr Kołaczkowski
> Priority: Minor
> Fix For: 2.0.1
>
> Attachments: pivot-graybox.patch

> When the applet starts, a progress bar is displayed. When the applet finishes
> downloading, the progress bar disappears, leaving a gray box until the pivot
> toolkit loads the application. Even for the simpliest application displaying
> an empty window, pivot requires about 0.3 s to start (on Core2Duo 2.2 GHz),
> so the gray box effect can be easily seen. The gray box effect does not
> happen always, but in about half of the cases.
> Below I submit patch we made to the BrowserApplicationContext.java file.
> Seems like setting the applet's background to white and delaying the
> add(displayHost) call as late as possible does the trick:
> [code]

> > private boolean displayHostInstalled = false;
> 151c152,154
> < add(displayHost);
> ---

> > // Don't add it now, add it later, to avoid ugly gray box:
> > //add(displayHost);
> 160c163,164
> < setBackground(null);

> > // Huh? WTF?
> > // setBackground(null);
