[jira] Commented: (ZOOKEEPER-268) tostring on jute generated
objects can cause NPE
[ https://issues.apache.org/jira/browse/ZOOKEEPER-268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12662117#action_12662117 ]
Mahadev konar commented on ZOOKEEPER-268:
-----------------------------------------
the patch looks good except a nit..
{code}
/** Cannot create a new instance of Utils */
private Utils() {
+ super();
}
{code}
why do we need to call super()? isnt it default object()?

> Jute still causing problems with tostring operations on generated code, need to review/cleanup the toCSV code
> From user Kevin Burton:
> ---------------------------------------------
> Creating this node with this ACL:
> Created /foo
> setAcl /foo world:anyone:w
> Causes the exception included below.
> It's an infinite loop so it's just called over and over again filling my
> console.
> I'm just doing an exists( path, true ); ... setting a watch still causes the
> problem.
