ONLY for Java based RI Apps (Guru, Cassini)
The default font (Helvetica) is not ideal for Java apps in OS/2 or eComStation. You may substitute them with better platform fonts to improve reliability.
In the directory d:\RiApps\jre141\lib\fontprop you will find the file "font.properties.alt1" (along with a few others). Copy the file to its parent directory with the name "font.properties" to change the default font set. The alt1 file has a particularly nice set of fonts.
Open an OS/2 Command window and type:
copy font.properties.alt1 ..\font.properties
