How to enhance BurpSuite (or any other Java app) font rendering

If we read Java - Better font rendering on ArchLinux wiki we can read this:

Both closed source and open source implementations of Java are known to have improperly implemented anti-aliasing of fonts. This can be fixed with the following options: -Dawt.useSystemAAFontSettings=on, -Dswing.aatext=true

So to fix font rendering in BurpSuite Pro for example, we just have to edit ~/BurpSuitePro/BurpSuitePro.vmoptions into:

1
2
3
4
5
6
7
8
9
# Enter one VM parameter per line
# For example, to adjust the maximum memory usage to 512 MB, uncomment the following line:
# -Xmx512m
# To include another file, uncomment the following line:
# -include-options [path to other .vmoption file]

-XX:MaxRAMPercentage=50
-Dawt.useSystemAAFontSettings=on
-Dswing.aatext=true

A note about anti-aliasing availability:

Anti-aliasing of fonts is available with Oracle Java 1.6 and OpenJDK on Linux.

For any other Java app call your Java app like this:

1
$ _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true' executable
