PersistenceManager.getObjectsById(Collection,boolean) throwing JDOException

I have a call to getObjectsById(Collection,boolean) that is throwing a JDOException the first time I'm attempting to retrieve an object. If I try again, then the second request succeeds.

The collection being passed in is a HashSet<Object> containing a single oid object (the method is written to support multiple objects, but it seems to only be failing irregularly when only a single oid is present). I'm passing false in as the verification argument. #1 2011-05-24 21:06 I have a call to getObjectsById(Collection,boolean) that is throwing a JDOException the first time I'm attemp ...
