ReplicationDriver & PreparedStatement

Hello,
I have a ClassCastException when I use a PreparedStatement with the replicationDriver ?

Any idea what's wrong ?

StackTrace:
Exception in thread "main" java.lang.ClassCastException: $Proxy4
at com.mysql.jdbc.ReplicationConnection.prepareStatement(ReplicationConnection.java:328)

My Code:
public static void main(String[] args) throws SQLException {

ReplicationDriver driver = new ReplicationDriver();

Properties props = new Properties();

// We want this for failover on the slaves
props.put("autoReconnect", "true");
props.put("roundRobinLoadBalance", "true");
props.put("user", Constants.USER);
props.put("password", Constants.PASSWORD);

Connection conn = driver.connect(Constants.URL,props);
conn.setReadOnly(true);
ResultSet rs = conn.createStatement().executeQuery("Select * from activity");
int numcols = rs.getMetaData().getColumnCount();
while(rs.next()) {
for(int i=1;i<=numcols;i++) {
System.out.print("\t" + rs.getString(i));
}
System.out.println("");
}

rs = conn.prepareStatement("Select * from activity").executeQuery();
numcols = rs.getMetaData().getColumnCount();
while(rs.next()) {
for(int i=1;i<=numcols;i++) {
System.out.print("\t" + rs.getString(i));
}
System.out.println("");
}

}
