I can't understand 'commons-dbcp uses static interfaces' mean from tomcat-dbcp menual -

-

i found tomcat-dbcp description tomcat web site. , could't understand below explanation.

  1. commons-dbcp uses static interfaces. means can't compile jdk 1.6, or if run on jdk 1.6/1.7 nosuchmethodexception methods not implemented, if driver supports it.

why static interface not able compile jdk 1.6? , why nosuchmethodexception invoked on jdk 1.6/1.7 ?
