I copied the 2nd jar back, and it seemed to work.
When I looked more closely, it appears that the first "jar" was actually a
broken symlink. I am not certain if that was something I did when I first
installed Grouper or not.

Copy the same jar to both folders  and see if it works.   Open a Jira if you

I ran the Grouper 2.2.2 upgrader to upgrade the Grouper api from 2.2.1 to
2.2.2. Near the end of the upgrade, I got the message:

There is a conflicting jar: ArrayList size: 2: [0]:

You should probably delete one of these files (oldest one?) or consult
the Grouper team.
Press <enter> to continue...

I ended up deleting the older file ([1] above). Now, when I try to use gsh,
I get a stack trace that indicates an issue with the database driver:

Grouper error: Error finding database driver class from com.mysql.jdbc.Driver, perhaps you did not put
the database driver jar in the lib/custom dir or lib dir, or you have the
wrong driver listed: java.lang.RuntimeException: Problem loading class:

I am guessing this is some kind of library versioning issue?
I can still connect to the DB if I use command line mysql with the same
