It's not a Karaf issue ;)
As you can see in bundle:headers, the package
com.fasterxml.jackson.module.afterburner.ser is not imported, so not in
the classloader: that's the issue.
Just add com.fasterxml.jackson.module.afterburner.ser in the Import-Package.

The Hello World Bundle is active:-

So bundle:headers is also showing correct wiring:-

Hello World (243)

Hi,
1. Can you check that the generated MANIFEST contains the

2. If you install afterburner bundle after your bundle, you
have to
refresh your bundle as it's an optional import

All the required Jackson bundles are installed in Karaf:-
|karaf@root>bundle:list | grep Jackson 123 | Active |
50 | 2.6.2 |
Jackson-core 125 | Active | 50 | 2.6.2 |
Jackson-annotations 238 |
Installed | 80 | 2.7.1 | Jackson-module-Afterburner
karaf@root>bundle:list | grep jackson 124 | Active | 50
| 2.6.2 |
jackson-databind |
Everything works fine if I just comment out the below
line:-
|objectMapper.registerModule(new AfterburnerModule()); |
I have placed the required code in github
<https://github.com/debraj-manna/afterburner-issue>
Has anyone able to execute the Jackson's Afterburner
module in
Karaf 3.0.5?
Thanks,
Debraj
