Grails Spring Security ACL kann Cache Bean nicht initiieren

Problem: Grails 2.5.0 kann aufgrund der folgenden Ausgabe nicht gestartet werden.

Please provide unique names for each CacheManager in the config or do one of following:
	1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
	2. Shutdown the earlier cacheManager before creating new one with same name.
	The source of the existing CacheManager is: DefaultConfigurationSource [ ehcache.xml or ehcache-failsafe.xml ]

Hintergund: Hibernate verwendet einen Cache und hat diesen bereits gestartet. Das ACL Plugin verwendet ebenfalls einen Cache unter dem gleichen Namen.

Lösung

Schritt 1: Ergänzen der Abhängigkeiten, um des Cache Plugin.

Schritt 2: Konfiguration des Cache, zur gemeinsamen Nutzung.

	import org.springframework.cache.ehcache.EhCacheManagerFactoryBean
	beans = {
	aclCacheManager(EhCacheManagerFactoryBean) {
	shared = true
	}
	}
