[WARNING] Rule 4: org.apache.maven.plugins.enforcer.EnforceBytecodeVersion
failed with message:
HBase has unsupported dependencies.
HBase requires that all dependencies be compiled with version 1.7 or earlier
of the JDK to properly build from source. You appear to be using a newer
dependency. You can use
either "mvn -version" or "mvn enforcer:display-info" to verify what version
is active.
Non-release builds can temporarily build with a newer JDK version by setting
the
'compileSource' property (eg. mvn -DcompileSource=1.8 clean package).
Found Banned Dependency: io.netty:netty-all:jar:4.0.52.Final
Use 'mvn dependency:tree' to locate the source of the banned dependencies.

Seems the newer netty bundles JCTools which was compiled with Java8. I guess
that means we have to back off the version of Netty a little bit to find a
version which doesn't have this.
