Check returned connection for null in JDBCRealm.open()
Per the Driver.connect(String, Properties) docs:
> The driver should return "null" if it realizes it is the wrong kind of driver
> to connect to the given URL.
I ran into this when I fat-fingered the JDBC URL's prefix (jdbc:msql: instead
of jdbc:mysql: with the MySQL driver). The offending code calls Driver.connect
and immediately calls setAutoCommit(false) on the resulting driver without
checking that the connect returned a connection.
I've attached a patch based from TOMCAT_6_0_18 that addresses the issue.
