MessageExchangeFactoryImpl NullPointerException

I am attempting to write unit level tests for our components who use a
DeliveryChannel by mocking out the ComponentContext and DeliveryChannel.
However I want to utilize the existing ServiceMix classes to create Exchange
Factorys and Message Exchanges. I am almost there but have hit a road block
with MessageExchangeFactoryImpl.setDefaults(MessageExchangeImpl exchange).
On line 260, setDefaults attempts to get the Marshaller. Since I am using a
MockComponentContext getContext returns null and I get a
NullPointerException. This is the line where it is occuring: 
PojoMarshaler marshaler = getContext().getActivationSpec().getMarshaler();

Would it be possible to check for null? Something like:


if (getContext() != null) {
    PojoMarshaler marshaler =
getContext().getActivationSpec().getMarshaler();
    if (marshaler != null) {
        exchange.setMarshaler(marshaler);
    }
}



Being able to write unit level tests without having to have ServiceMix
running would provide HUGE benefits for our team. And this currently appears
to be the only stumbling block.

Thanks.

Thanks for getting that resolved so quickly.

Do you have an estimate as to when the next release will be created?
The SNAPSHOT directory appears to have been created last around 06-20.
