> David Daney (David.Daney@avtrex.com) reports a bug with a severity of 3
> The lower the number the more severe it is.
>
> Short Description
> JDBC driver security issue.
>
> Long Description
> The JDBC driver requires
>
> permission java.lang.RuntimePermission "shutdownHooks";
>
> in the policy file in order to function. However the driver does not protect the shutdown hooks call in an
AccessController.doPrivileged()call, so these permissions must be granted to all code not just the postgres JDBC
driver.

> Sample Code
