Here is a web page from Sun that specifies the minimum that a driver must
implement to be compliant with the JDBCTM

A.1.6 Support Multithreading
All operations on java.sql
and javax.sql objects are required to be multithread safe. They must be

should not block an execution in another thread. In particular, JDBC
drivers should operate correctly when used from multiple threads.
