Develop CacheSPI impl for use in JBoss JMX microkernel
------------------------------------------------------

                 Key: JBCACHE-832
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-832
             Project: JBoss Cache
          Issue Type: Task
      Security Level: Public (Everyone can see)
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
             Fix For: 2.0.0.GA


If we want JBC 2.0 to work in AS 4.2, we'll need a way to construct a CacheSPI via the 4.x microkernel/SARDeployer.

Initial thoughts:

1) Create class "CacheSPIWrapper" that implements CacheSPI, plus exposes all the configuration-related mbean attributes from JBC 1.4.  This is the class that's used for the "class" attribute of the mbean in the -service.xml file.
2) Class when instantiated also instantiates a Configuration object.  When SARDeployer invokes the setters on the legacy mbean attributes, the values are passed through to the Configuration object.
3) In createService(), the Configuration object is passed to DefaultCacheFactory, which returns an instance of the standard CacheSPI impl. CacheSPIWrapper holds a ref to this object for use as a delegate.
4) CacheSPIWrapper implements CacheSPI by delegation to the standard object.

If we decide we don't want to support use of JBC 2.0 in 4.2, this task can be closed.
