[jira] Commented: (ZOOKEEPER-240) Yet another npe

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

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-240?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651074#action_12651074 ] 

Patrick Hunt commented on ZOOKEEPER-240:
----------------------------------------

Jute generated toString methods rely on CSVOutputArchive which in turn relies on Jute's Utils.java. the toCSVBuffer doesn't check for null buffer, which it should.

Note: if you fix this (add null check to toCSVBuffer) please be sure to review the rest of the code in Utils.java for similar problem(s).
