Re: Fabric creates multiple DB connections

I went into the source code of FabricMySQLConnectionProxy.java and i think the problem is in the implementation of this line.

protected Map<ServerGroup, ReplicationConnection> serverConnections = new HashMap<ServerGroup, ReplicationConnection>();

ServerGroup object does not override hashCode() and equals() method.
I put a debug point in the middle of my application run and the size of the map was 1424. It should be not more than 4 since i have 1 global group and 3 HA groups.

I am using mysql-connector-java-5.1.36

Can anyone from Oracle/MySql look into this?
