I have a simple Hello World type Karaf Bundle. The activator code looks like below:-
public class HelloWorldActivator implements BundleActivator {
@Override
public void start(BundleContext bundleContext) throws Exception {
System.out.println("STARTING DEMO: hello, world\n");
System.out.println(getJsonDataAsString());
}
@Override
public void stop(BundleContext bundleContext) throws Exception {
System.out.println("STOPPING DEMO");
}
private String getJsonDataAsString() {
JsonDataBlob jsonDataBlob = new JsonDataBlob();
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new AfterburnerModule());
try {
return objectMapper.writeValueAsString(jsonDataBlob);
} catch(Exception e) {
e.printStackTrace();
}
return "";
}
}
pom.xml looks like below:-

The java object which I am trying to convert to json is a simple object as shown below:-
package com.hello.world;
public class JsonDataBlob {
private String add1 = "JP Naagar";
private String add2 = "";
private int shippartagent = 1;
public String getAdd1() {
return add1;
}
public void setAdd1(String add1) {
this.add1 = add1;
}
public String getAdd2() {
return add2;
}
public void setAdd2(String add2) {
this.add2 = add2;
}
public int getShippartagent() {
return shippartagent;
}
public void setShippartagent(int shippartagent) {
this.shippartagent = shippartagent;
}
}
Whenever I am trying to install the bundle I am getting the below exception:-

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());
Let me know if you want me to check the source code to be checked into github for reproducing it on your end.
