I don't know if it is a bug or not, but I learned today that org.apache.tomcat.jdbc.** is a different tomcat implementation from the default dbcp based implementation (org.apache.tomcat.dbcp.**). And, you seem to use the former one. Therefore, I think you should file a bug in tomcat, not in commons-dbcp, IMHO: - http://tomcat.apache.org/bugreport.html
