Tests fail for arm

[stevef1uk]

This library is used by the fabric8 docker-maven-plugin which produces the error:

ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.14.3-SNAPSHOT:build (default-cli) on project java-fatjar: Execution default-cli of goal io.fabric8:docker-maven-plugin:0.14.3-SNAPSHOT:build failed: An API incompatibility was encountered while executing io.fabric8:docker-maven-plugin:0.14.3-SNAPSHOT:build: java.lang.UnsatisfiedLinkError: could not load FFI provider jnr.ffi.provider.jffi.Provider

Trying to build this on a RPi3 built ok but produces the following errors:
