Make the annotation @Management works in association with @Singleton

In JBoss 5.1, the use of @Management in association with @Service allowed to manage (JMX Management) the singleton EJB.

In JBoss 6.0 Final, @Service annotations can be replace by the JEE6 standard annotation @Singleton.

The problem is that the @Management annoation does not work if used in association with the @Singleton annotation.
