> When upgrading from 4.0.0 to 4.1.0 the upgrade fails when the DB contains
> CLOBS of zero length with the following error
> ERROR:
> ORA-22994: source offset is beyond the end of the source LOB
> ORA-06512: at "SYS.DBMS_LOB", line 978
> The reason for this is that DBMS_LOB.CONVERTTOBLOB does not handle zero
> length CLOBs correctly.
> The fix is to explicitly check for the lob.length and skip those when doing
> the conversion
