Dear all,
Thank you very much for your comments.
I would like to be able to upgrade from my outdated Java 7u91 (x86 32-bit)
to at least Java 12, but I have some device driver libraries that are x86
32-bit only and I can not instantiate them anymore via JNI with the x86
64-bit version.
Regards,
Andre
