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:
# 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=trueA 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:
$ _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true' executable
