> Hi,
> We have discovered a bug in OpenJPA when InverseManager is used with collection annoted @toMany([...], optional = false). OpenJPA doesn't solve inverse relation before calling here internal preflush method.
> This bug does not exist on 2.1.0 and 2.1.1.
> A unitary test and a small patch is worth a thousand words ;) [1]
> [1] Patch successfully tested on OpenPJA 2.2.1 and in our software.
> Regards,
