Removed the ClientCacheFactoryBean.readyForEvents() method and moved the logic to onApplicationEvent(..).
Updated the spring-gemfire 1.6 and 1.7 XSD with the new keep-alive attribue on the client-cache element.
Changed the generic signature of the CacheFactoryBean class back to com.gemstone.gemfire.cache.Cache due to the Spring container bean resolution Exception when using JavaConfig in SDG 1.7 with GemFire 8.1 and core Spring Framework 4.1.7.
