Michael Dürig updated OAK-1909:
-------------------------------
Description:
We are doing some testing with active-active on mongomk. We have some code that creates a
node and the same node can be created by multiple instances/threads/whatever. The node will
look exactly the same regardless of who creates it, and we don't care who creates it, we just
want it to exist. On mongomk, if 2 threads create the same node, we get an InvalidItemStateException.
I would have expected an ItemExistsException, based on
http://www.day.com/maven/jsr170/javadocs/jcr-2.0/javax/jcr/Node.html?is-external=true
To repro, run this code in 2 threads:
{code}
try {
retBucketNode = root.addNode(name, nodeType);
session.save();
} catch (final ItemExistsException e) {
//…handle the failure via session.refresh(false)…
}
{code}
Note that you get an InvalidItemStateException instead of the expected ItemExistsException.
