Subject Re: [Math][ALL] Travis failing (with JDK7 but not JDK8)
Date Wed, 09 Aug 2017 22:23:23 GMT
I would start by updating the Maven plugins and any third party deps.

For example:

[INFO] --- maven-jgit-buildnumber-plugin:1.2.10:extract-buildnumber
(default) @ commons-math4 ---

[ERROR]

org.eclipse.jgit.errors.RevWalkException: Walk failure.

Why not try updating maven-jgit-buildnumber-plugin to the current version?
