Jackrabbit 1.4.9 - Multiple transactions over single session?

[Lei Zhou <Le...@pointalliance.com>]

Hi, 
I'm getting intermittent StaleItemStateException when updating a 
collection of nodes repeatedly. The first run of the use case never fails. 
But second or third run would fail on same set of data. 
Wonder how JR handles such use cases and what needs to be paid attention 
to? 
The exception output below: 

Caused by: org.apache.jackrabbit.core.state.StaleItemStateException: 
14229e16-a57c-42f3-91ba-a307c1b60ec9/{}DocumentReferences has been

                 at 
org.apache.jackrabbit.core.state.XAItemStateManager.prepare(XAItemStateManager.java:144)

My use case is as below: 

Begin Transaction(xid1)
   check out nodes
Commit Transaction(xid1)

Begin Transaction(xid2)
   update nodes/delete nodes
Commit Transaction(xid2)

Begin Transaction(xid3)
   check in nodes if exist
Commit Transaction(xid3)


Thanks.
