JuPnP NPE - Cannot invoke "Object.toString()" because the return value of "org.jupnp.model.state.StateVariableValue.getValue()" is null

I updated to snapshot 3838 this morning and now I'm getting the following flooding out my logs. Nothing on my network has changed recently. I was on 3820 (I believe) prior to this and I did not have this issue. I cleared cache and that had no effect.
