JCache ACL Cache for Spring Security

I'm using Spring Security ACL and it needs to have cache defined. So far I was using this:

@Bean(name = { "defaultAclCache", "aclCache" })
protected AclCache defaultAclCache() {
    return new SpringCacheBasedAclCache(defaultAclJCacheFactory(), defaultPermissionGrantingStrategy(), defaultAclAuthorizationStrategy());
}

and it all worked fine. However, I switched to use jcache and now defaultAclJCacheFactory() returns an instance of javax.cache.Cache which is incompatible with the SpringCacheBasedAclCache:

@Bean(name = { "defaultAclJCacheFactory", "aclJCacheFactory" })
protected Cache defaultAclJCacheFactory() {
    return cacheManager.getCache("acl_cache");
}

I tried to search for a JCache implementation of org.springframework.security.acls.model.AclCache but there's only this one for spring cache and one for EhCache. Is there any plans to introduce one for jcache?

You should be able to use JCacheCacheManager implementation to obtain an instance of org.springframework.cache.Cache For example:

@Bean(name = { "defaultAclCache", "aclCache" })
protected AclCache defaultAclCache(org.springframework.cache.CacheManager springCacheManager) {
    org.springframework.cache.Cache cache = 
        springCacheManager.getCache("acl_cache");
    return new SpringCacheBasedAclCache(cache, 
        defaultPermissionGrantingStrategy(), 
        defaultAclAuthorizationStrategy());
}

// Depending on your configuration, you may not even need this
@Bean
public JCacheCacheManager springCacheManager(javax.cache.CacheManager cacheManager) {
    return new JCacheCacheManager(cacheManager);
}
