MySQL connection does not work when slave db is down using sql connector 5.1.39

[pavan challa]

We are using Java with a MySQL database. My SQL connector - 5.1.39.

URL :

jdbc:mysql://host1:port1,host1:port2/schema?allowSlaveDownConnections=true&loadBalanceBlacklistTimeout=50000&readFromMasterWhenNoSlaves=true

In the above URL, host1:port1 is the master and host1:port2 is the slave db .

Now, from the SQL connector - 5.1.38 , the parameter - allowSlaveDownConnections=true, should allow the connections even when the slave is down.

But practically, when the slave is down, the connection is not going through at all and getting a "connection timed out" error.

Please assist me in solving this issue. The goal is to get the app working even when the slave is down.
