It is probably because of inconsistence between bundles/plugins versions, so I tried to change parent from 4.4.2.AM1-SNAPSHOT to 4.4.2.Final-SNAPSHOT which was used in 10.2.0.GA I guess.

Unfortunatelly it has not solved my problem, tycho has been still installing another version of org.eclipse.osgi bundle. So I tried to apply same fix as in JBDS-4077
