Hi
I am getting the exception ClassCastException: java.util.TreeSet , for
the code "cache.attach("datamodel",dataModel);" I am using JBossCache
'Habanero' 2.0.0.GA. Kindly help! It is a blocking condition for our project!

Code:
String configFile = "resource/replSync-service.xml";
PojoCache cache = PojoCacheFactory.createCache(configFile);
cache.start();
Object obj=cache.find("datamodel");
DataModel dataModel;
if(obj!=null)
{
dataModel=(DataModel) obj;
}
else
{
dataModel= new DataModel();
DatabaseController.loadFromDatabase(dataModel, loadDates);
cache.attach("datamodel",dataModel);
}
