Actually, the instructions _do_ say how to turn off the verifier:

"Because of the implementation of java.sql.Savepoint, Connector/J 3.1.0 and newer will not run on JDKs older than 1.4 unless the class verifier is turned off (-Xverify:none), as the class verifier will try to load the class definition for java.sql.Savepoint even though it is not accessed by the driver unless you actually use savepoint functionality."

You need to pass '-Xverify:none' as a startup option to your JVM.
