CacheConfig(CacheSimpleConfig simpleConfig) constructor broken in 3.4

[kutsal]

Looks like @asimarslan forgot to fix variable assignments in this commit. This prevents JCache declarative initialization given a configuration XML containing entries for cache-writer-factory or expiry-policy-factory:

java.lang.ClassCastException: javax.cache.expiry.AccessedExpiryPolicy cannot be cast to javax.cache.integration.CacheLoader

Here's the broken code in question:

    public CacheConfig(CacheSimpleConfig simpleConfig) throws Exception {
        ...
        if (simpleConfig.getCacheLoaderFactory() != null) {
            this.cacheLoaderFactory = ClassLoaderUtil.newInstance(null, simpleConfig.getCacheLoaderFactory());
        }
        if (simpleConfig.getCacheWriterFactory() != null) {
            this.cacheLoaderFactory = ClassLoaderUtil.newInstance(null, simpleConfig.getCacheWriterFactory());
        }
        if (simpleConfig.getExpiryPolicyFactory() != null) {
            this.cacheLoaderFactory = ClassLoaderUtil.newInstance(null, simpleConfig.getExpiryPolicyFactory());
        }
        ...
    }
