ClassNotFoundException: org.hyperic.sigar.Sigar during tests execution

I have the following exception in logs during tests execution:

If we add Sigar project as dependency, it will not help completely:

<dependency>
    <groupId>org.fusesource</groupId>
    <artifactId>sigar</artifactId>
    <version>1.6.4</version>
</dependency>

Sigar project uses binary libraries, so it's necessary to do some additional tricks.

This exception has a lowest severity (TRACE) in logger. I believe we can ignore it safely.
