[jira] Commented: (JDO-552) JDOFatalDataStoreException, JDOObjectNotFoundException and JDOOptimisticVerificationException dont allow nested exceptions and failed objects together

["Craig Russell (JIRA)" <ji...@apache.org>]

Craig Russell commented on JDO-552:
-----------------------------------

This is by design. The rationale for having a failed object is that this is the object that was responsible for the exception, and the assumption is that once an object has an exception for the current operation, it is considered failed and no further action is taken.

The rationale for a Throwable[ ] is that many JDO operations act on multiple objects, and each object might have a different reason for failing. So the pattern is that each object is attempted and if it fails, the exception is added to the Throwable[ ]. 

Can you give an example where you would have a failed object that was not one of the failed objects in the Throwable[ ]?
