--------------------------------------
Hi [~gnt],
Thanks for looking into this issue.
Please see the reproducer(say-more-spring.tar) I just attached, extract and
build it.
Then with a clean Apache Karaf 4.1.3 kit, run commands from karaf console
{code}
repo-add camel 2.20.2
feature:install aries-blueprint-spring camel-spring camel-netty-http
camel-jackson
bundle:install -s mvn:com.mycompany/say-more-spring/1.0.0-SNAPSHOT
{code}
wait a few seconds in the karaf.log we can see the exception like
{code}
Caused by: java.lang.IllegalArgumentException: Data format 'json-jackson' could
not be created. Ensure that the data format is valid and the associated Camel
component is present on the classpath

IMO this is caused by the camel-spring has no OSGi support so that we cannot
use OsgiComponentResolver, OsgiDataFormatResolver which are "OSGi aware".
Btw, my previous suggested fix is [1](this was reverted although it works, and
we may need to use a separate module since it introduce OSGi dependency to
camel-spring), which just add some crucial classes back from the removed
camel-spring-dm module.
If we rewrite the reproducer with blueprint, then everything works great. we
can send a request
{code}
curl -X POST -d "{ \"name\": \"Jack\" }" -H "Content-Type: application/json"
http://localhost:10000/say/greeter
{code}
and get expected response
{code}
{"response":"SUCCESS","errors":["warn1","warn2"]}

> the spring-dm won't work with spring 4.x, and there's a new blueprint-spring
> introduced in Aries to make the spring configured bundle still work with
> spring 4.x
> We need add back CamelContextFactoryBean.java and OsgiSpringCamelContext.java

> with the bundle in OSGi.
> We need remove spring-dm dependency from those classes.
