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.ser was not getting imported even though the top level package com.fasterxml.jackson.module.afterburner was getting imported?
