             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.8.2.2
         Environment: OSX 10.6
            Reporter: Paul taylor


Im seeing this error occur after loading alot of data into the Database. I can confirm that autocommit is set to off, and that it occurs on calling  rs.next() immediatlely after running a query and assigning to  resultset rs. The cdoe is called many times (250,000) and usually works, then suddenly it starts going wrong, I also using c3po database pooling. Im wondering if the problem is linked to memory consumption although I have no OutOfMemoryError occurring
  
Java.sql.SQLException: ResultSet not open. Operation 'next' not permitted. Verify that autocommit is OFF.
