[jira] [Comment Edited] (OAK-1846) ConstraintViolationException:
OakConstraint0030: Uniqueness constraint violated for key <>
[ https://issues.apache.org/jira/browse/OAK-1846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14348652#comment-14348652 ]

---------------------------------------------------------------
The conflict resolution between Oak and Jackrabbit 2 is definitely different:
In Oak: If a node exists already at that place where it is about to be imported (but having a different UUID), the node is replaced by the one from the import with the UUID from the imported node, but no conflict handling at all is triggered (i.e. the method resolveUUIDConflict is not called, https://github.com/apache/jackrabbit-oak/blob/trunk/oak-jcr/src/main/java/org/apache/jackrabbit/oak/jcr/xml/ImporterImpl.java#L488), even if there is a node somewhere in the repository already having that ID.
For Jackrabbit 2: The conflict resolver is always triggered, whenever the a node with the same ID exists somewhere in the repository (https://github.com/apache/jackrabbit/blob/trunk/jackrabbit-core/src/main/java/org/apache/jackrabbit/core/xml/SessionImporter.java#L408). Even in case the imported node does already exist with a different id.
