The PropertiesFileLicenseLogTest is failing on Jenkins after the move to Docker.
The javadoc for File#canWrite https://docs.oracle.com/javase/8/docs/api/java/io/File.html#canWrite-- grew the following text in 8: "On some platforms it may be possible to start the Java virtual machine with special privileges that allow it to modify files that are marked read-only. Consequently this method may return true even though the file is marked read-only."
It appears that our Docker contains meet this condition. I will therefore add a new skip condition if this is the case as the test is not valid.
