It's exactly related to the refresh caused by several combination of
jackson.
That's why it would be better to have a jackson feature provided by
karaf and third parties using it to have versions aligned.

org.apache.karaf.features.core - 4.3.3 | Bundles to refresh:
The problem is caused by different versions of jackson-annotations
bundle in the system:
98 | Active | 35 | 2.11.4 |
mvn:com.fasterxml.jackson.core/jackson-annotations/2.11.4
99 | Active | 80 | 2.12.4 |
mvn:com.fasterxml.jackson.core/jackson-annotations/2.12.4
2.11.4 comes with feature cxf-jackson (version 3.4.5) into the system
2.12.4 comes activemq 5.16.3 into the system.
When I patch the hawtio feature and set the version number of the
jacksons bundle from 2.12.3 to 2.12.4 the installation of the hawtio
feature takes 4 seconds.

Hi,
When you do feature:install -v, do you see lot of refresh happening ?
I will do feature:install -tv to check the resolver output (it could
depend of your runtime, what's installed in there).
