Hi! It seems that I suffer from the same problems which got reported in OPENJPA-525 [1] while trying to write null value to a not null field. It seems that OpenJPA magically converts it to an empty string, thus I get NO Exception in MySQL and I DO get an exception in Oracle (because Oracle treats empty VARCHAR strings as null).
Is there any integration test or unit test which proves OPENJPA-525? If I'd like to write such a test, where should I add it? txs and LieGrue, strub [1] https://issues.apache.org/jira/browse/OPENJPA-525
