Method DistributedSession.getDescriptor(Class) cause NPE in InstanceVariableAttributeAccessor.getAttributeValueFromObject(Object) line 80:return this.attributeField.get(anObject);

public ClassDescriptor getDescriptor(Class domainClass) {
ClassDescriptor descriptor = getDescriptors().get(domainClass);

// If the descriptor is null then this means that descriptor must now be read from the server.
if (descriptor == null) {
descriptor = getRemoteConnection().getDescriptor(domainClass);
if (descriptor == null) {
return null;
}
getDescriptors().put(domainClass, descriptor);
descriptor.remoteInitialization(this);
}

return descriptor;
}

This method put class descriptor in a map before it is remotely initialized. Using that descriptor in a other thread gives NPE in InstanceVariableAttributeAccessor. Field InstanceVariableAttributeAccessor.attributeField is initialized in a method ClassDescriptor.remoteInitialization()
