Just this week I upgraded from karaf-1.2.6 and pax-jdbc-1.3.1 to 
karaf-1.2.8-SNAPSHOT and pax-jdbc-1.4.4 and I didn’t run into any issues.

Stupid question, but can you confirm that the Migrator class is instantiated 
and that the component is active?

        com.*.Migrator in bundle 129 (db.init:1.0.0.SNAPSHOT_20200122-1230) 
enabled, 1 instance.
            Id: 18, State:ACTIVE

Initially I missed some Package-Imports on the migrator bundle which left the 
component in the SATISFIED (I believe) state. After scrolling through the logs 
I discovered a CNFE which pointed me in the right direction.
