/**
* {@link FactoryBean} that obtains a WebSphere {@link javax.management.MBeanServer}

* available on WebSphere 5.1 and higher.

* Exposes the {@code MBeanServer} for bean references.
* This FactoryBean is a direct alternative to {@link MBeanServerFactoryBean},
* which uses standard JMX 1.2 API to access the platform's MBeanServer.
