fat jar wrongly detected on simple jar

[seboudry]

Description

Using a simple jar packaging (with Spring-Boot in my case), fabric8-maven-plugin incorrectly detect it as a fat-jar.

After looking on recent fmp code changes, I noticed this Main Class test deletion
7795450#diff-6381c00c0fdfd17f4c36d06e76549dcfL61

Is it really wanted for JIB support?
