ArrayIndexOutOfBoundsException in ApplicationIds

[Udi]

Hey,
I just upgrated my OpenJPA version from 1.0.1 to 1.2.0, and I get ArrayIndexOutOfBoundsException in ApplicationIds.
I have an embedded entity, that has a ManyToOne field. I noticed that in some point when i'm loading the manyToOne field, it takes the _owner class and tries to retrieve its PK.
The thing is the embedded has no PK and then the exception is thrown.

Any ideas?

thanks,
Udi

I found the reason - OPENJPA-815.
