A bit more Googling helped me find this topic: 
https://forums.freebsd.org/viewtopic.php?t=44098

Someone recommends "portdowngrade", which seems to allow me to install 
an earlier version. He wrote "I found that b27 has been the last stable 
Java in my Serviio media center. On b28, Java doesn't close files and 
eventually pegs the kern.maxfilesperproc sysctl 
<http://man.freebsd.org/sysctl>. On b29, Java causes kernel panics on 
9.2-RELEASE. Portdowngrade is your friend in situations like this."

Is this a bad idea?

Thanks for any advice!
