> I had strange case. Running:
> {noformat}
> for n in {1..100}; do
>     mvn clean install -DskipTests -f /path/to/custom-karaf-distro
>     cp /path/to/custom-karaf-distro/target/assembly/etc/config.properties /data/tmp/config-$n.properties
>     cat /path/to/custom-karaf-distro/target/assembly/etc/config.properties | sort > /data/tmp/config-$n-sorted.properties
> done
> {noformat}
> I was _usually_ getting the same config.propertie. But not always. Occasionally some extra packages were missing...
> Long story short, downloader uses 8 threads and {{org.apache.karaf.profile.assembly.Builder#downloadLibraries()}} uses the download callback without any synchronization...
