> If null ACLs are passed then zk node creation fails with NPE
> {code}
> java.lang.NullPointerException

> Below APIs have problem.
> {code}
> public void create(final String path, byte data[], List<ACL> acl,
> CreateMode createMode, StringCallback cb, Object ctx)
> public void create(final String path, byte data[], List<ACL> acl,
> CreateMode createMode, Create2Callback cb, Object ctx)
> {code}
> Solution:
> a) Need to handle NULL ACLs in removeDuplicates method in server.
> b) Also add the client side validation for null / empty ACL for above API similar to other create API
