[jira] Commented: (ZOOKEEPER-487) setdata on root (/) crashes the servers.

["Patrick Hunt (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735222#action_12735222 ] 

Patrick Hunt commented on ZOOKEEPER-487:
----------------------------------------

Wow, this sucks. :-) Good catch.

Re a 3.1.2, since this is deterministic, and the first anyone has noticed, I think we should be
safe saying prior to 3.2.1 "don't set data on / znode" and leave it at that. It's pretty
atypical anyway and should be easy to work around - set "/root" (whatever) instead.

> setdata on root "/" crashes the servers with the followimg exception. Unfortunately we never had a setdata test on root. The following is the exception. This happens with 3.1.1 as well. We might want to consider releasing 3.1.2 just for this jira.
