Key: JCR-1940
URL: https://issues.apache.org/jira/browse/JCR-1940
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 1.5.0
Environment: OS - Win 2000
JackRabbit Jars - 1.5
Reporter: Richa Khurana
Priority: Blocker
We have a enabled jackrabbit clustering. In this mode following exception
occurs when 2 users simultaneouly add documents to Jack rabbit repository
registered with node id 1 and 2 respectively-
14:59:55,312 ERROR [DocumentHelper] Exception occurred while adding a manually
uploaded document to the jackrabbit:
javax.jcr.InvalidItemStateException: cafebabe-cafe-babe-cafe-babecafebabe has
been modified externally
at org.apache.jackrabbit.core.ItemImpl.save(ItemImpl.java:1109)
at org.apache.jackrabbit.core.SessionImpl.save(SessionImpl.java:846)
Another observation is that when we disable clustering and both users have same
node id in cluster configuration in repository.xml, the error doesnt appear.
