Error messages could certainly be better, and please call my attention
to any patches to this effect that have not gotten their due attention.
The particular error message in question here comes from Java, and is
more informative on more recent versions of Java. I get:
java.lang.ClassCastException: user.proxy$java.lang.Object$TableModel
$521c1983 cannot be cast to clojure.lang.IFn
This is pretty specific: it says that you are trying to use an
instance of a Java proxy as an IFn.

But that doesn't address the fundamental lack of useful information in
the error messages, which is something I've noticed as well. The
compiler could stand to be a bit friendlier in this regard..

You have an extra pair of parens around the proxy call which will
treat
the proxy as function which won't work.
Try this:
(import 'javax.swing.JTable 'javax.swing.table.TableModel)
(def table (JTable. (proxy [TableModel] []
(getColumnCount [] 10)
(getRowCount [] 10)
(getValueAt [row column] (* row column)))))
