> DatabaseMetaData.usesLocalFiles() returns true for in-memory databases. And it also returns
true for DatabaseMetaData.usesLocalFilePerTable(). The following script shows this:
> {noformat}
> connect 'jdbc:derby:memory:db;create=true';
> call syscs_util.syscs_register_tool( 'databaseMetaData', true );
> values usesLocalFiles();
> values usesLocalFilePerTable();
> {noformat}
> I think that these methods should return false because an in-memory database does not
store tables in files.
