> Since updates made to a BLOB or CLOB value in Derby is made on a copy, DatabaseMetaData
.locatorsUpdateCopy() call should return true.  For the embedded driver the functionality
to update a LOB value is new in 10.3. For the client driver, updates have been possible in
prior releases, and locatorsUpdateCopy() has returned false.  That behavior was wrong since
the client updated a main-memory copy, not the values in the database.  For 10.3, the client
will use a locator based implementation which will rely on the behavior of the embedded driver.
 Hence, locatorsUpdateCopy() should return true in both cases.
