Description

Similar to CAMEL-5950, but only occurs at lazy cache initialization.

net.sf.ehcache.ObjectExistsException: Cache sampleCache already exists
    at net.sf.ehcache.CacheManager.addCacheNoCheck(CacheManager.java:1294) ~[org.apache.servicemix.bundles.ehcache-2.5.2_1.jar:na]
    at net.sf.ehcache.CacheManager.addCache(CacheManager.java:1184) ~[org.apache.servicemix.bundles.ehcache-2.5.2_1.jar:na]
    at org.apache.camel.component.cache.CacheEndpoint.initializeCache(CacheEndpoint.java:137) ~[camel-cache-2.10.3.jar:2.10.3]

Workaround:

		for (Endpoint endpoint : context.getEndpoints()) {
			if (endpoint instanceof CacheEndpoint) {
				CacheEndpoint ce = (CacheEndpoint) endpoint;
				ce.initializeCache();
			}
		}
