Prevent export from overwriting existing files
----------------------------------------------
Key: DERBY-2925
URL: https://issues.apache.org/jira/browse/DERBY-2925
Project: Derby
Issue Type: Sub-task
Components: Security, Tools
Affects Versions: 10.2.2.0, 10.1.2.1, 10.3.1.3, 10.4.0.0
Reporter: Kathey Marsden
Export should not overwrite existing files, but rather insist that the user
remove them before writing to the file. This will help prevent accidental or
intentional corruption of the database with export. This may introduce a
compatibility issue with export but because export is usually an attended
utility and not typically invoked as part of an application, I think the risk
is worth the additional security this will provide.
