I have issues with the versions of Narayana TM on Karaf. There is incorrectly defined transaction-manager-narayana feature's version at 5.7.2 because it depends on pax-transx-tm-narayana:0.2.0 feature which contains JARs from 5.6.3.Final.

https://github.com/ops4j/org.ops4j.pax.transx/blob/pax-transx-0.2.0/pom.xml#L157
https://github.com/jboss-fuse/karaf/blob/4.2.x.redhat-7-0-x/pom.xml#L257

We need to use 5.5.30.Final-redhat-1 version of TM which is productized by EAP 7.1 and should be used by Spring Boot too (ENTESB-7132).
