Subject [jira] Commented: (JCR-2433) NPE when copying nodes with Workspace.copy()
Date Tue, 11 May 2010 21:43:43 GMT

    [ https://issues.apache.org/jira/browse/JCR-2433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12866355#action_12866355
] 

Jukka Zitting commented on JCR-2433:
------------------------------------

I have now (as of revision 943301) backported/reimplemented most of the JCR-2170 changes in
the 1.6 branch. These changes should also solve this  issue. At least I was no longer able
to reproduce the problem with the repository Paul sent me.

Note that this revision includes a backward-compatible change in how item states are serialized,
which makes the repository unreadable by earlier Jackrabbit 1.6.x versions. I'll see if I
can prevent this incompatibility as patch releases should be both backward- and forward-compatible
with all releases from the same maintenance branch (e.g. in addition to normal upgrades, it
should be OK to also switch back from 1.6.2 to 1.6.1).

> It seems that it happens not all the time. The error occurs since we use Jackrabbit 1.6.0.
We do not get the error with previous versions. It seems that we only get the error when trying
to copy nodes that were created with Jackrabbit 1.4 and copied with Jackrabbit 1.6.
