 * <pre class="code">
 * static class OnJndiAndProperty extends AllNestedConditions {
 *
 *    OnJndiAndProperty() {
 *        super(ConfigurationPhase.PARSE_CONFIGURATION);
 *    }

 *    }
 *
 * }
 * </pre>
 * <p>
 * The
 * {@link org.springframework.context.annotation.ConfigurationCondition.ConfigurationPhase
 * ConfigurationPhase} should be specified according to the conditions that are defined.
 * In the example above, all conditions are static and can be evaluated early so
 * {@code PARSE_CONFIGURATION} is a right fit.
