Why? Isn’t the point in an environmental variable that its, well… variable? > If $OPENSHIFT_DATA_DIR later changes > because they shuffle my VM or something, then the system property will > still refer to the old location until I figure out there's a problem > and go reset the system property. I don’t really understand this. You’re saying that $OPENSHIFT_DATA_DIR changes but your Java program keeps running? That’s not going to work. > Long story short, I'd like some way to programmatically set the font > cache directory, so I can run something like > FileSystemFontProvider.setDiskCacheFile(...) before I do anything else > with PDFBox. That’s not going to be possible, firstly because FileSystemFontProvider is not public and secondly because it relies on a static initializer, which does not allow for the opportunity to call any methods beforehand. > Would you accept a patch to add that to FileSystemFontProvider?
