@44898 - issue 1:

1. Register this hook:
public class SessionHook
implements InitTermListener
{
   public void initialize()
   {
      Persistence persistence = PersistenceFactory.getInstance("p2j_test");
      RecordIdentifier ident = null;

      try
      {
         boolean beganTx = persistence.beginTransaction();

         Long pk = (Long) persistence.nextPrimaryKey("book");
         ident = new RecordIdentifier("book", pk);
         persistence.lock(LockType.EXCLUSIVE_NO_WAIT, ident, true);

         BookImpl book = new BookImpl();
         book.setBookId(new integer(9999));
         book.setBookTitle(new character("Some book"));
         book.setCost(new integer(10));
         book.setPrice(new integer(10));

         persistence.save(book, pk);
         if (beganTx)
         {
            persistence.commit();
         }
      }
      catch (PersistenceException exc)
      {
         System.out.println(exc);
      }
      finally
      {
         if (ident != null)
         {
            try
            {
               persistence.lock(LockType.NONE, ident, true);
            }
            catch (LockUnavailableException exc)
            {
               // unexpected
            }
         }
      }
   }

   public void terminate(Throwable t)
   {
   }
}

2. Run a simple testcase that uses permanent buffers, e.g.
find first book no-lock.

@44899 - isuue 1 (cont):

3. You will the following exception when performing RecordBuffer.openScope(book):

Probably happens because openBuffers does not have a proper scopes added.
