Adding camel-jackson dependency creates issues with inner classes

[mmistretta]

When adding the camel-jackson dependency, comments with imports, actual imports, etc inner classes are no longer found.

version: Camel K Client and Operator 1.0.0-RC2
Example: https://github.com/jeremyrdavis/quarkus-cafe-demo/commits/camel-k-addition
- commit works: d95b5ea360ca1dabe333b2ce568fc87b18e8594d
- commit does not work: 4ee524f4ccf2c9dce3005b80e7fa44b4d1546528

Process on OpenShift 4.4:

• Create project
• Install camel k operator
• kamel install --olm=false --skip-cluster-setup --skip-operator-setup --maven-repository https://jitpack.io@id=jitpack@snapshots
• kamel run --name=rest-with-undertow --dependency=camel-rest --dependency=camel-undertow --dependency=mvn:com.github.jeremyrdavis:quarkus-cafe-demo:1.2-SNAPSHOT RestWithUndertow.java

This should not be an issue any-more in camel-k 1.0.0

The issues was caused by a bug in the jOOR library which is used to compile the Java integration at runtime which is included in jOOR's 0.9.13 [1]. The camel-k-runtime version used by camel-k RC2 is
1.1.0 [2] which dos not includes the fix [3]

[1] jOOQ/jOOR#99

[3] https://github.com/apache/camel-k-runtime/blob/camel-k-runtime-parent-1.1.0/pom.xml#L42

@mmistretta can you please confirm ?

@mmistretta I've finally been able to find the root cause, here the related issues:

• https://issues.apache.org/jira/browse/CAMEL-15199
• Create a CompositeClassloader and set is as Camel's ApplicationClassloader camel-k-runtime#364

I think we can close this now that we have all the pieces released
