When you use *, maven-bundle-plugin/bnd is checking the actual import in
your byte code. Here, you "really" import
com.fasterxml.jackson.module.afterburner, but the ser package is not in
your byte code, but transitively to the afterburner package. That's why
it's not imported by the wildcard (because not directly used in your code).

Thanks Jean. Updating the import as below in pom.xml solved the issue:-
<Import-Package>com.fasterxml.jackson.module.afterburner.ser;resolution:=optional,*</Import-Package>
Can you please let me know even though I specified * in the
Import-Package why com.fasterxml.jackson.module.afterburner.serwas not
getting imported even though the top level
packagecom.fasterxml.jackson.module.afterburnerwas getting imported?

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.

Hi,
1. Can you check that the generated MANIFEST

2. If you install afterburner bundle after your

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
