Kristian Waagan updated DERBY-1318:
-----------------------------------

    Attachment: serialized-data-sources.zip
                derby-1318-1b-for_comments.stat
                derby-1318-1b-for_comments.diff

'derby-1318-1b-for_comments.diff' is a slightly changed from 1a:
 * uses more specific versions (for instance 10.3.2.1 instead of 10.3)
 * improved documentation slightly
 * added a read method to SerializeDataSource.java, which prints information about the specified file.

Also added the serialized data source files, which are not included in the diff because they are binary files.

> Currently, our DataSources are serializable in order to play well with JNDI. However, we have no upgrade test verifying that DataSource serialization works across release boundaries. We should add this case to our upgrade tests.
> Further recommendations by Dan:
> "I do think though that upgrade testing recently brought into the mainline by Deepa should be enhanced to test:
>    - serializing Derby''s data source implementations in 10.1 and seeing it unserializes with 10.2
>       (maybe into a BLOB column)
>   - making a Reference object out of Derby''s data source implementations in 10.1 and making it into
>      an object with 10.2. (if this type of tetsing makes sense for References')"
