Cannot connect to multiple different cache clusters via ExtendTCP

Question

Hi,
I'm trying to have two different ExtendTCP configurations for accessing different cache clusters, but I cannot get it to work. Essentially, the server configurations look like this:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
<caching-scheme-mapping>
<cache-mapping>
<cache-name>testcache1</cache-name>
<scheme-name>testcache1-distributed</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<distributed-scheme>
<scheme-name>testcache1-distributed</scheme-name>
<lease-granularity>member</lease-granularity>
<backing-map-scheme>
<local-scheme/>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>
<proxy-scheme>
<scheme-name>testcache1-proxy</scheme-name>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>5</thread-count>
<acceptor-config>
<tcp-acceptor>
<local-address>
<address>localhost</address>
<port>9098</port>
</local-address>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>
</proxy-scheme>
</caching-schemes>
</cache-config>
and
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
<caching-scheme-mapping>
<cache-mapping>
<cache-name>testcache2</cache-name>
<scheme-name>testcache2-distributed</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<distributed-scheme>
<scheme-name>testcache2-distributed</scheme-name>
<lease-granularity>member</lease-granularity>
<backing-map-scheme>
<local-scheme/>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>
<proxy-scheme>
<scheme-name>testcache2-proxy</scheme-name>
<service-name>ExtendTcpProxyService</service-name>
<thread-count>5</thread-count>
<acceptor-config>
<tcp-acceptor>
<local-address>
<address>localhost</address>
<port>9099</port>
</local-address>
</tcp-acceptor>
</acceptor-config>
<autostart>true</autostart>
</proxy-scheme>
</caching-schemes>
</cache-config>
And the client configuration looks like this:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
<caching-scheme-mapping>
<cache-mapping>
<cache-name>testcache1</cache-name>
<scheme-name>testcache1-remote</scheme-name>
</cache-mapping>
<cache-mapping>
<cache-name>testcache2</cache-name>
<scheme-name>testcache2-remote</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<remote-cache-scheme>
<scheme-name>testcache1-remote</scheme-name>
<service-name>ExtendTcpCacheService</service-name>
<initiator-config>
<tcp-initiator>
<remote-addresses>
<socket-address>
<address>localhost</address>
<port>9098</port>
</socket-address>
</remote-addresses>
<connect-timeout>10s</connect-timeout>
</tcp-initiator>
<outgoing-message-handler>
<request-timeout>5s</request-timeout>
</outgoing-message-handler>
</initiator-config>
</remote-cache-scheme>
<remote-cache-scheme>
<scheme-name>testcache2-remote</scheme-name>
<service-name>ExtendTcpCacheService</service-name>
<initiator-config>
<tcp-initiator>
<remote-addresses>
<socket-address>
<address>localhost</address>
<port>9099</port>
</socket-address>
</remote-addresses>
<connect-timeout>10s</connect-timeout>
</tcp-initiator>
<outgoing-message-handler>
<request-timeout>5s</request-timeout>
</outgoing-message-handler>
</initiator-config>
</remote-cache-scheme>
</caching-schemes>
</cache-config>
Now the problem is that Coherence apparently only creates the first tcp initiator, and when I try to access the second cache 'testcache2', Coherence looks for this cache in the remote cache identified by this first tcp initiator, which obviously does not have this cache. Accessing 'testcache1' works just fine.
This is the output:
2007-11-13 11:15:19.676 Oracle Coherence GE 3.3/387p4 <D5> (thread=main, member=n/a): Started: TcpInitiator(Running=true, ThreadCount=0, PingInterval=0, PingTimeout=5000, RequestTimeout=5000, ConnectTimeout=10000, RemoteAddresses=[172.16.16.248:9098], KeepAliveEnabled=true, TcpDelayEnabled=false, ReceiveBufferSize=0, SendBufferSize=0, LingerTimeout=-1)

Btw, this is with version 3.3 patch 5.
Is there something wrong with my configurations, or is this a bug in Coherence ?
Any help appreciated,
Tom

Hi Tom,
You need to use difference service names:
<?xml version="1.0"?>
<!DOCTYPE cache-config SYSTEM "cache-config.dtd">
<cache-config>
    <caching-scheme-mapping>
        <cache-mapping>
            <cache-name>testcache1</cache-name>
            <scheme-name>testcache1-remote</scheme-name>
        </cache-mapping>
        <cache-mapping>
            <cache-name>testcache2</cache-name>
            <scheme-name>testcache2-remote</scheme-name>
        </cache-mapping>
    </caching-scheme-mapping>
    <caching-schemes>
        <remote-cache-scheme>
            <scheme-name>testcache1-remote</scheme-name>
            <service-name>ExtendTcpCacheService1</service-name>
            <initiator-config>
                <tcp-initiator>
                    <remote-addresses>
                        <socket-address>

                    <connect-timeout>10s</connect-timeout>
                </tcp-initiator>
                <outgoing-message-handler>
                    <request-timeout>5s</request-timeout>
                </outgoing-message-handler>
            </initiator-config>
        </remote-cache-scheme>
        <remote-cache-scheme>
            <scheme-name>testcache2-remote</scheme-name>

                <tcp-initiator>
