OK, Here's what I did. With sample blueprint.xml with *two* contexts (one bad,
one correct):
{code:xml}
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";>
<camelContext xmlns="http://camel.apache.org/schema/blueprint";>
<route id="r1">
<from
uri="timer://simpleTimer?period=1000&repeatCount=0&funnyopt=1" />
<setBody> <simple>Hello World 1</simple> </setBody>
<to uri="log:test" />
</route>
</camelContext>
<camelContext xmlns="http://camel.apache.org/schema/blueprint";>
<route id="r2">
<from uri="timer://simpleTimer?period=1000&repeatCount=0" />
<setBody> <simple>Hello World 2</simple> </setBody>
<to uri="log:test" />
</route>
</camelContext>
</blueprint>
{code}
I've installed it using {{install -s blueprint:file:///data/tmp/blueprint.xml}}
and saw:

> Bundle in 'Active' State but Camel Context not initialized

>
> Key: CAMEL-12980
> URL: https://issues.apache.org/jira/browse/CAMEL-12980
> Project: Camel
> Issue Type: Bug
> Components: camel-blueprint
> Affects Versions: 2.20.1, 2.21.1
> Reporter: Xilai Dai
> Assignee: Grzegorz Grzybek
> Priority: Critical
> Fix For: 3.0.0, 2.24.0
>
> Attachments: blueprint.xml
>
>
> The camel context can't get initialized when validation of the
> RouteDefinition failed (e.g. typo in Uri or add an unsupported option in
> Uri), but when deploy the blueprint, the CamelContext startup and then
> shutdown, but the bundle status is still 'Active', only a
> FailedToCreateRouteException ERROR is logged.
> 318 │ Active │ 80 │ 0.0.0 │ blueprint.xml
> Attached the simple blueprint.xml for reproduce it.
> The expected behaviour is the bundle is in the 'Failure' status in this case.
> The fix proposal from my side is, move the call of "this.maybeStart()" from
> blueprintEvent() method to the constructor of the BlueprintCamelContext
> class. then this kind of Route definition error can be processed during the
> Blueprint "CREATING" phase. Currently, the start() is invoked after Blueprint
> in "CREATED" phase. (I tested this fix locally and have the expected
> 'Failure' bundle status)
> (This issue is found in Camel 2.20.x, 2.21.x, but it may affects also on
> master branch)
