I just remembered something.

cjb> * Staging Server - after rollback
cjb> JRE 8u171, 32 bit

We tried to do the upgrade 9/18/18 and then rolled back.
But I remember now, in my periodic testing on 9/4/18, a compile error, for
which I decided to keep a copy of the stack trace (please see below). So
something *did* happen before we even started messing with the server 2 days
ago. But I didn't follow up on it - oops, see where that got me.
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 1 in the generated java file
The type java.io.ObjectInputStream cannot be resolved. It is indirectly
referenced from required .class files
