Thank you very much Nikolai.
I understand. Fonts can be very large so keeping them in memory just like that is
probably not a good idea. I recon you use the java.io.RandomAccessFile class, so a
compromise that perhaps has only a local impact on the code is to copy a font file
to a temporary file and use java.io.RandomAccessFile on that. The copies would be
alive as long as the XEP instance is. This is, of course, only a suggestion that
crosses my mind.
I was not complete in my previous posting, because the ROOT property should allow
URLs as well. Otherwise the configuration would remain global, while some resources
it configures, such as fonts, would be application-local.
