Обсуждение: Fw: java.lang.IndexOutOfBoundsException when commit long transaction

Hello.

 I'm trying to implement data replication mechanism base on OpenJPA and WebServices.
 When I tried to persist about 200000 objects that references each other i have got an error on commit:

 I use PostgreSQL 8.2 as database and openJPA 1.0.1 as ORM.
 Can anybody help me? As i see problem lies in Postgre Driver. My current is postgresql-8.2-505.jdbc3.jar

That's an unusual error and does look like it is the driver's problem.
Are there any errors prior to this one?  Can you reproduce it with a
smaller test case or only with 200000 records?  If you can put together
something self contained, I'd love to look at it.  Another good diagnostic
tool is adding ?loglevel=2 to your connection URL to enable verbose
logging.  With 200k records that's going to be a lot of info, but if
you're willing to share it, I'd be willing to take a look at that too.
