Mark Wielaard: New GPG key.
Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create. pub 2048R/57816A6A 2011-01-29 Key f...

This Java Tech Column provides instruction on overlaying lightweight Swing widgets on top of heavyweight AWT components using a TransparentPanel.
When overlaying lightweight Swing widgets on top of heavyweight AWT components, it is convenient to group the Swing widgets on a transparent (non-opaque) JPanel so that one can use Swing layout managers and/or Swing utilities on a group of related Swing widgets. For example, all widgets added to the transparent JPanel can be made visible or invisible simultaneously with one setVisible() call on the JPanel. Unfortunately, a lightweight JPanel overlaid on top of a heavyweight AWT component cannot be transparent.
To overcome this problem, one can implement a TransparentPanel as shown below.
