[FABRIC-1057] Make Fabric8 compile with JDK8
FAB tests migrated from Scala to Java. They still don't work on JDK8 (OSGi/ASM/Aries problem)
FAB: Migrated tests work well with JDK7
Insight component doesn't contain Scala at all
Change of POM names (to make the build log prettier)
All XML-related stuff + tests rewritten in Java6 code
No more Scala in camel-tooling-util. Alignment of Maven versions for test deps
No more Scala in mq-fabric
Add accessExternalSchema option to cxf-codegen to make it work under JDK8
Unify POM names
Removing com.weiglewiczek deps (scala-library 2.11.1 is proper OSGi bundle)
Updating CuratorZookeeperClient to align with curator-2.4.2
Could this be the only mistake while replacing Scala with Java?
No, it isn't - this is final mistake
Downgrading Scala version for gateway-core
