 * Andrei Ilitchev May 28, 2008. Bug 224964: Provide support for Proxy Authentication through JPA.
 *     Changed the was Proxy Authentication supported in case of thin driver, but support for oci case remains the same.
 *     That caused re-arranging of the tests: before the fix all the tests were directly in proxiauthentication package;
 *     now the old tests (minus thin-specific setup) were moved into the new proxyauthentication.oci package,
 *     and the new tests defined in the new proxyauthentication.thin package.
