new connection implicitly created when autoReconnect was disabled

I am experiencing some strange behavior related to "autoReconnect" parameter.

Here are the steps for a simple test i have run:

1 - get a connection from driver (having autoReconnect=false in the url)
2 - execute an sql
3 - make the master (primary) server unavailable (i.e. unplug network cable)
4 - execute sql on the connection (SHOULD fail)
5 - execute sql on the same connection again (SHOULD fail)
* monitor tcp connections throughout the test. NO connections to slave host should be opened.

url: jdbc:mysql://dbmaster,dbslave:3306/TESTDB?autoReconnect=false&connectTimeout=5000&socketTimeout=30000&relaxAutoCommit=true&

connector/j : 5.1.18 (and 5.1.22 with same results)

java: 1.6(.0.37)

I assumed that connector/j would not automatically "reconnect" a connection when autoReconnect was disabled.

But it seems that a connection is created against the slave(dbslave) at step 5. (at which the connection had already received a communications exception)

any comments?
