Compilation errors on Maven build

[crapo]

I cloned the repo and ran a Maven build. I get these two errors, which I also get if I import the code into Eclipse as a Maven project:
[ERROR] COMPILATION ERROR :

I see you are using java9+ to compile (java11?).
There is no such thing as java.lang.Module in java8 (ONT-API is java8-based API).

It seems right now there is no possibility to compile the whole project against java11.
But (I just checked) you can build it without tests: mvn11 clean package -Dmaven.test.skip=true.
Or use java8.

As for the compilation errors,
the first class can be improved to be valid in java11 too (actually, it's strange why this class is not understood by a more fresh compiler, but that code is bit dirty);
the second class is a part of spin-tests, and it is better to remove it at all (#24 )
