Injection metadata validation on deploy-time is too aggressive

If your war file includes Pojo whose field is annotated with @Resource, deployer throws Exception below:

Scanning is ok, but validation is too aggressive.
In JBoss AS 4, such @Resource usage is allowed and it can be utilized by Spring etc.
