Preface
I'm using Karaf to deploy some Camel routes. I'm currently using the deploy folder for that. My issue is that Karaf takes a very long time to start up the first time with the contents in my deploy folder, which I will list shortly. Without these contents, the startup is pretty fast. On subsequent starts, the error doesn't appear. I start Karaf via karaf.sh with debugging enabled.
Versions
- JDK: AdoptOpenJdk/OpenJDK8
- Karaf Version: 4.2.6
- Camel Version: 3.0.0-M1
- Target of my beans: Java 1.8
Provisioning
I'm using these files for provisioning.

My deploy folder currently has these contents:
- A JAR file with camel beans (23KB)
- A KAR file with its dependencies (2.7MB)
- A blueprint file in which I use the above camel beans (15KB)
I also get this error when I try to start Karaf, this actually appears a second time directly following the first:

What I did so far
- Reinstall Karaf
- I upgraded to this version of Karaf
- I tried installing OpenJDK9, 11
- I analyzed my transitive dependencies and found that some of them target Java 1.9
The error stays. Karaf and my Camel routes work correctly after Karaf is started, I just don't like seeing this error. Would it make sense for my camel application to target 1.9? Upgrading would be a huge process, maybe you can see something from the things I've provided before I go about requesting to target 1.9.
