I'm back on my project involving Scott Klement's JDBCR4. And I ran into
a problem.

I have a table, in a MySQL database, with a column of type "MEDIUMTEXT"
(which I understand to be some sort of CLOB). Squirrel (which is using
the exact same JDBC driver that JDBCR4 is using) sees it as a
MEDIUMTEXT, SequelPro (which is MySQL-centric) sees it as a MEDIUMTEXT.

But my JDBCR4 application sees it (calling the
ResultSetMetaData.getColumnTypeName method; I don't remember whether
Scott front-ended that method in the standard JDBCR4, or whether I had
to front-end it myself) as a VARCHAR, albeit with an impossibly huge
maximum size.

Can anybody offer me any insights?

I believe the documentation calls MEDIUMTEXT a TEXT type, not a xLOB
type. It specifically says this: 'Similarly, you can regard a TEXT
column as a VARCHAR column.'
http://dev.mysql.com/doc/refman/5.0/en/blob.html

Is there some specific issue treating MEDIUMTEXT as VARCHAR?
