---------------------------------

Hi Kristian or Knut:
    Would you mind provide any information to 6b patch which has Kristian's piggy backing change of session data change cause TestConnReuse to give exception on Connection.setTransactionIsolationX at the first connection when the isolation level is TRANSACTION_READ_COMMITTED? Thanks, Lily

> With in EmbedConnection.setIsolation() we have a check to see if the isolation level is the same and if so just return without doing a commit:
>   public void setTransactionIsolation(int level) throws SQLException {
> 		if (level == getTransactionIsolation())
> 			return;
> with org.apache.derby.client.am.Connection we have no such check. It would be good if the client driver acted like embedded.
