It is indeed surprising that these methods are @CS. It seems this has 
been the case since JDK 1.1/1.2 then the java.sql API was changed from 
using the security context. It needs to be re-examined along an 
investigation on the impact of changing this after all these years.

As Lance Andersen often points outs, most EE/web applications are likely 
to be using javax.sql.DataSource rather than java.sql.Driver these days.
