12  * This integration is usually performed by BeanValidationIntegrator.
13  * Unfortunately, that integration will only be activated upon
14  * initialization of the ServiceRegistry, which initializes
15  * DatasourceConnectionProviderImpl, which looks up the datasource,
16  * which requires a JNDI context ...
17  * We therefore reimplement the relevant parts of BeanValidatorIntegrator.
18  * Since that must occur after secondPassCompile(), which is invoked by
19  * Configuration.generateSchemaCreationScript, which is invoked by
20  * SchemaExport, some fancy subclassing is needed to invoke the integration
21  * at the right time.
