-------------------------------------
Thanks for the PR but it causes a test to fail now in camel-test-blueprint.
Also it would be good if you could do an unit test that validates your use-case.

> Project: Camel
> Issue Type: Bug
> Components: camel-blueprint
> Affects Versions: 2.15.1
> Environment: Camel 2.15.1.redhat-620133
> JBoss Fuse 6.2.0.redhat-133
> openjdk version "1.8.0_45"

>
> When BlueprintPropertiesParser parses an "augmented" property key that is not
> found (i.e. value is null), it does not return the null value so that the
> fallbackToUnaugmentedProperty="true" (default) behavior can run. Instead, it
> immediately throws an IllegalArgumentException.
> As a result, it appears to be impossible to take advantage of
> fallbackToUnaugmentedProperty="true" behavior when using the Blueprint
> properties resolver/parser.
> I discovered this against Red Hat's JBoss Fuse impl of Camel, but am
> reporting it here because it appears to be a bug in base Camel. More details
> in comments.
