Introduction
This fix makes your Java apps use your GTK+ theme (colours & such) & your chosen font settings. Here is how it looks like:

How do you do it?
First try if the outcome is what you expect:
1) Set the variable _JAVA_OPTIONS accordingly:
export _JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel ${_JAVA_OPTIONS}"
2) Run your Java app from the same terminal window.
If the result looks good to you, let us make the changes permanent:
1) Append the above definition of the _JAVA_OPTIONS variable to ~/.profile (for your user only) or /etc/profile.d/90-java_ops.sh (system-wide). If the file does not exist, create it.
2) Restart the system
3) Start your Java app to check the result.
4) If, for some reason, the entry in ~/.profile or /etc/profile had no effect, you can put the following line into /etc/environment:
_JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel -Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel ${_JAVA_OPTIONS}"
