The ACL expression is of the form addr/bits?

[IKumasa Mukai]

I cannot set ACL with the form "ip:addr/bits".
Cannot I use this type of form as the ACL expression?

setAcl /test ip:192.168.0.0/16:cdr

Exception in thread "main"
org.apache.zookeeper.KeeperException$InvalidACLException:
KeeperErrorCode = InvalidACL for /test
