         [Deprecated] This extension point is used to support the extension of BIRT design time and runtime data source access.  Each extension must implement the BIRT Open Data Access (ODA) Java runtime interfaces defined in the &lt;i&gt;org.eclipse.birt.data.oda&lt;/i&gt; package.
&lt;p&gt;
&lt;b&gt;As of BIRT 2.0, the BIRT ODA run-time framework has been migrated to the Eclipse Data Tools Platform (DTP) project.
It is replaced by the &lt;i&gt;org.eclipse.datatools.connectivity.oda.dataSource&lt;/i&gt; extension point.
&lt;br&gt;BIRT 2.0 provides a DTP-to-BIRT ODA adapter plug-in to support
existing ODA run-time extensions that implemented this extension point.

                  If true, the consumer of the ODA runtime extension plug-in should set the thread context class loader to the one used to load this driver before calling any ODA interface method.
In BIRT release 1, any data source extension with this flag set to true would take precedence, and is applied to all data source extensions implemented by this plug-in. 

In BIRT Data Engine, the thread context class loader being set is the OSGi class loader used to load this ODA runtime plugin.  It is not designed to be used by a plugin to in turn load additional classes.  If further class loading is needed, it is up to individual ODA runtime plugin implementation to provide its own URLClassLoader, and switch thread context class loader as appropriate.
