This is a test case I wrote using Junit to show the bug.  It needs a breakpoint to show the threading problem.

> When adding an object to PojoCache, AdvisedPojoHandler attaches a CachedFieldInterceptor to the advised object being added.(line 125)  It does this before it adds the object to the actual Cache.   If another thread reads this object in between the time the CachedFieldInterceptor is added and the object is inserted into the cache, (line 178) an exception will be thrown in the Reading thread:org.jboss.cache.pojo.PojoCacheAlreadyDetachedException: pojo: class org.jboss.cache.pojo.test.Person has possibly been detached remotely.
