      Description

      When a PositionedStoreStream is created on top of a stream from store, it must properly initialize itself.
      Proper initialization consists of initializing and resetting the stream to make sure the states of the streams are in sync.

      A case of out of sync stream states was detected in a test where the Clob reference wasn't kept, but a new Clob object was created for each operation, i.e:
      rs.getClob(1).length();
      rs.getClob(1).getSubString(...);

      A symptom of out of sync stream states is EOFException on a valid request.
      I don't think the access style above is supposed to work, but the proper initialization should be performed anyway.
