["Goerler, Adrian" <adrian.goerler@xxxxxxx>]

 

Hi,

 

I have not received any feedback on this. Could anyone please have a look at the proposed patch so that I can proceed with it (or look for an alternative solution)?

 

Thanks,

Hi,

 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=327472

 

this issue is due to a particularity in the order, which MaxDB uses to lock tables in the presence of FK constraints. Seems that MaxDB can't change this.

 

I am proposing to use a native query on MaxDB to assert that pessimistic locking with lock scope EXTENDED guarantees repeatable read on the join table (as required by the spec).

 

Could you please have a look?

 

Thanks,

 

Adrian
