DatabaseJournal improperly finds tables in external schemas when used on Oracle

The DatabaseJournal currently calls database metadata to determine if the journal table has already been created. It uses the following code to do so:

ResultSet rs = metaData.getTables(null, null, tableName, null);

The Oracle driver sometimes will return the table if it is in another schema on the same database. Other DBMS code within JackRabbit has a specific Oracle version that handles this case. In order for the journal table to be properly created, Oracle databases will need the schema name included in the getTables() call.
