More Info

The build is running on a slave  
Jenkins ver. 1.565.2
Tried with both maven 3.0.4, and 3.1.1
Tried with surefire 2.16, 17 & 18
Tried with junit 4.10 & 4.11 

I have verified the SHA1 of JUnit jar in the Maven repository and made sure the jar file is not corrupted. 

Command line
(defined in a jenkins job)
clean install -P FastTests -DIsBuildSystem=1 -T 4 -X -e

Relevant parts from the parent pom.xml
The project itself is a multi module pom project, with the parent pom defining the surefire definitions as attached.
