Java 8 Maven build and test failure

[GoogleCodeExporter]

To keep track of this, and in case someone else has a similar issue, on Java 8 
the Maven build will fail with the ouput shown below. The problem seams to be 
related to the sorting of collections in the test. 

Java on Ubuntu:
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

The failure looks like this:
