JBossSessionPolicyDecorator currently extends from JBossServiceBeanMetadata such that it can represent as such transparently. However, none of the JBossServiceBeanMetadata methods are handled back to the underlying delegate, so they're either NOOP or return null.

Change the architecture to extend into a JBossServicePolicyDecorator to provide support for these operations.

Defining use case is that metadata.getManagement() is returning null when backed by JBossSessionPolicyDecorator, leading to regressions in the noted Environment.
