+/**
+ * <a href ="https://issues.apache.org/jira/browse/OPENJPA-40">COPY FROM OPENJPA-40</a>
+ * OpenJPA-specific SimpleLoadTimeWeaver which excludes all the core
+ * <em>org.apache.openjpa</em> packages from being instrumented. This
+ * is important, since enhanced classes will wind up implementing
+ * <em>org.apache.openjpa.enhance.PersistenceCapable</em>, so it there
+ * is a mismatch between the PersistenceCapable that is loaded by the
+ * system classloader and the one that is loaded by the 
+ * instrumenting ClassLoader, then OpenJPA will not function properly.
+ *
+ * <p>
+ *
+ * This loader can be specific by including the following in the 
+ * spring configuration XML as follows:
+ *
+ * <p>
+ *
+ * <code>
+ *  &lt;bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"&rt;
+ *  ...
+ *    &lt;property name="loadTimeWeaver"&rt;
+ *        &lt;bean class="oorg.apache.myfaces.tobago.example.addressbook.OpenJpaLoadTimeWeaver"/&rt;
+ *    &lt;/property&rt;
+ *    &lt;/bean&rt;
+ * </code>
