Ouf ! I'm not insane, (at least regarding this bug :))) I just realized that when I explicitly register the driver, there are now two instances begin added:
Clojure user=> (println (enumeration-seq (. java.sql.DriverManager getDrivers))) ([EMAIL PROTECTED]) ;; No instance registered nil user=> (clojure.lang.RT/classForName "com.mysql.jdbc.Driver") com.mysql.jdbc.Driver user=> (println (enumeration-seq (. java.sql.DriverManager getDrivers))) ([EMAIL PROTECTED]) ;; Still no instances registered nil user=> (java.sql.DriverManager/registerDriver (new com.mysql.jdbc.Driver)) nil user=> (println (enumeration-seq (. java.sql.DriverManager getDrivers))) ([EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED]) ;; Two instances registered nil user=> I suspect the static class code to be executed when I register the driver on top of the registration itself: This means that (clojure.lang.RT/classForName "com.mysql.jdbc.Driver") has no effect on the static code in the class. This is done in the sql contrib library but it has no effect on the list of registered drivers. However: Clojure user=> (println (enumeration-seq (. java.sql.DriverManager getDrivers))) ([EMAIL PROTECTED]) nil user=> (new com.mysql.jdbc.Driver) [EMAIL PROTECTED] user=> (println (enumeration-seq (. java.sql.DriverManager getDrivers))) ([EMAIL PROTECTED] [EMAIL PROTECTED]) ;; Ah ! Ah ! nil user=> does the job. Static code in the class is not executed by calling Class.classForName.
