Subject [jira] [Commented] (OAK-110) NPE in KernelNodeStoreBranch.diffToJsop
Date Wed, 23 May 2012 11:32:40 GMT

    [ https://issues.apache.org/jira/browse/OAK-110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13281528#comment-13281528

Jukka Zitting commented on OAK-110:
-----------------------------------

Good catch, thanks!

I think it's a bit better if these cases are handled already in the NodeStateBuilder instead
of the resulting modified NodeState. I adjusted the code accordingly in revision 1341833.

> The NPE is causes by the diff algorithm introduced with OAK-109 passing {{null}} to {{NodeStateDiff.propertyAdded()}}
and {{NodeStateDiff.childNodeAdded()}}. This happens when a transiently added node/property
is again removed.
