Minor Description
In EmbedStatement.java the execute(String, String[]), execute(String, int[]), executeUpdate(String, String[]), and executeUpdate(String, int[]) methods treat a 0-length array to mean NO_GENERATED_KEYS. But in EmbedConnection.java the prepareStatement(String, String[]) and prepareStatement(String, int[]) methods treat a 0-length array to mean RETURN_GENERATED_KEYS. For the sake of consistency, the two classes should treat 0-length arrays in the same way--which probably means changing EmbedConnection to match EmbedStatement.
