java - Shiro's clearCachedAuthenticationInfo is null

Question

When shiro executes clearCachedAuthenticationInfo, the following problems occur:

protected void clearCachedAuthenticationInfo(PrincipalCollection principals) {
    if (!CollectionUtils.isEmpty(principals)) {
        // return null
        Cache<Object, AuthenticationInfo> cache = this.getAvailableAuthenticationCache(); 
        if (cache != null) {
            Object key = this.getAuthenticationCacheKey(principals);
            cache.remove(key);
        }
    }

}
