I was having the same problem. But I think it was because of the transaction 
timeout issue. I reperformed the claiming activity, the error was gone. 
But I have another issue. 
In my web application I am having two tabs for the inbox. One for the tasks 
pending with the user and other for the tasks of the roles(whose status is 
ready and can be claimed). Basically these two are user inbox and role inbox 
respectively. The issue is even when I am claiming the task in the database the 
task status is not changed. Its ready only. So its not coming in the user 
inbox(owned tasks) instead coming in the role inbox only. When I am claiming 
the task again. I get an error saying the status of the task is not matched and 
sometimes I get the above error.

When I digged dipper into the task, I found that the after I claim the task the 
task status is not persisted in the database and in the hibernate cache for 
that particular task object the status is different(Reserved). So while getting 
the tasks from the database I get the claimed task in the role inbox not in the 
user inbox.

The similar issue I found with the complete task API.
I am using the following code for completing the task 





 ***public
**
* **static** **void** completeTask(**long** taskId, Map data, String userId) 
**throws** InterruptedException {
//connect();
















++tService++.start(taskId, userId);
ContentData contentData = 
**null**; 




**if** (data != *null*) {
ByteArrayOutputStream bos = 
**new** ByteArrayOutputStream();ObjectOutputStream out;





**try**
{

#
out =
**new** ObjectOutputStream(bos); 

out.writeObject(data);out.close();


contentData = 
**new** ContentData(); 
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.+Inline+
);} 




**catch**
(IOException e) {
e.printStackTrace();
}
}





++tService++.complete(taskId, userId, contentData); 



//responseHandler.waitTillDone(5000);

}



#
#



If I pass a null Map object to the above method I am getting the similar issue. 
The task status is not changed. Its still reserved only.
