Subject Re: IndexOutOfBoundsException in SQLBuffer in OpenJPA 1.3.0-SNAPSHOT-r422266:724815
Date Mon, 15 Dec 2008 19:15:15 GMT

Forgot to say that this same query works fine in the version of OpenJPA
shipped with WebSphere v6.1.  It fails in a very similar way on the version
of OpenJPA shipped with WebSphere 7.0, which is why I tried downloading the
latest 1.3.0 version.  Let me know if you need copies of the entities that
I'm trying to fetch.
