You are right. I changed the sequenceName to xxx and it works...

Thx for help :)

Hi Christopher,

As it turns out, I don't think this problem is the same as OPENJPA-1259.
There is special code in the PostgresDictionary that treats sequences
suffixed with "_SEQ" as system managed sequences.  The comment in
PostgresDictionary.isSystemSequence reads:

       // filter out generated sequences used for bigserial cols, which are
       // of the form <table>_<col>_seq

This explains why the same code worked for me on DB2.  Are you able to
modify the sequence name?  (ex. sequenceName = "seq_obj_item_id")  If not,
please file a new JIRA.   It may/should be possible to make the code a bit
smarter by actually verifying _seq suffixed sequences are for a bigserial
column[1] instead of just making the assumption.
