David Daney ([EMAIL PROTECTED]) 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
Here is a diff that fixes the problem.
