Fast Failover property prevents container restart

Question

I'm running a 10.1.3.1 Application Server using the managed data sources using
connection pooling which connect to a 10.1.0.4.0 Database in a clustered RAC
environment. (Before our recent migration from the 9.0.4 application server, we used
the oc4j startup parameter to use the fast failover.)
After I added the fastConnectionFailoverEnabled property to the connection pool,
my container will not start and gives me the following error:
The following topology members could not be restarted due to errors:
* OC4J ADSPL in Application Server appserver.ydoraias1.corp.ad.awiweb.com
due to the following error:
o 0 of 1 processes restarted.
Trying to access the container from the OEM console gives me this error:
Unable to login to the OC4J "ADSPL" on Application Server "appservername". The version of this OC4J is not supported.
I have not found anything in the log files to determine the problem.
here's the data source xml
<?xml version = '1.0' encoding = 'UTF-8'?>

I think you also need to set this additional property:
<property name="connectionCachingEnabled" value="true"/>
<property name="fastConnectionFailoverEnabled" value="true"/>
Below is a data-sources entry from a file I have used recently:
<managed-data-source connection-pool-name="RACDB" jndi-name="jdbc/RACDS-SCOTT" name="RACDS-SCOTT"/>
<connection-pool name="RACDB" initial-limit="10" max-connections="30" min-connections="10">
<connection-factory factory-class="oracle.jdbc.pool.OracleDataSource" user="scott" password="tiger" url="jdbc:oracle:thin:@ (DESCRIPTION= (LOAD_BALANCE=ON) (ADDRESS= (PROTOCOL=TCP) (HOST=192.168.203.11) (PORT=1521)) (ADDRESS= (PROTOCOL=TCP) (HOST=192.168.203.111) (PORT=1521)) (CONNECT_DATA=(SERVICE_NAME= RACDB)))">
<property name="connectionCachingEnabled" value="true"/>
<property name="fastConnectionFailoverEnabled" value="true"/>
</connection-factory>
</connection-pool>
