Just tried that , here is my observations.
1. There is no classcast exception in the jvm running stand alone cache client
2. The Jconsole mbean view of the treecache , under the attibutes tab I see the following attributes as red.
Name Value
a. Instance Unavailable (in red font on hovering the mouse it shows the following exception ...
//java.rmi.unmarshalexception error unmarshalling return , nested exception is java.io.WriteAbortedException, writing aborted; java.io.NotSerializableException; org.jboss.cache.TreeCache
b. Interceptors
c. members
3. when I click on the operation tab the jconsole throws following exceptions
Error setting Operation panel :org.jboss.cache.TreeCacheListener
Error setting Operation panel :org.jboss.cache.TreeCacheListener
Error setting Operation panel :org.jboss.cache.Fqn
Error setting Operation panel :org.jboss.cache.Fqn

I am using following java version
C:\Documents and Settings\shgoe>java -version

Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing)
Jboss cache stand alone client code (Sleep is introduced just for it to wait for the jconsole to connect)
public class SampleTreeCache {
public static void main (String[] a)
{
SampleTreeCache sampleTreeCache = new SampleTreeCache();
TreeCache cache1 = null;
try
{
cache1 = sampleTreeCache.createCache();
cache1.put("/jboss-cache-manager", "Sample Cache Entry", "This is a sample");
Thread.currentThread().sleep(600000);
}catch(Exception e)
{
e.printStackTrace();
}
}
private TreeCache createCache() throws Exception
{
TreeCache cache = new TreeCache();
PropertyConfigurator config = new PropertyConfigurator();
config.configure(cache, "invalidationSync-service.xml");
System.out.println("Tree cache configured with META-INF/invalidationSync-service.xml ");
cache.startService();
