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 ---


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

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

To which version?
Isn't this supposed to be defined in the "parent"?

You can check


This link confirms that 1.2.10 is the latest version of the
tool used by Commons Math's POM.

Then, there is another (with a different GroupId) that is at
1.2.11. I'll try that one...

Done, didn't change a thing:

Build with Java 8 runs fine:

But with Java 7:

Is anyone willing to debug this failure?

1) Bug in maven-jgit-buildnumber-plugin - rather noisy when it cannot
find the current git info

That's not what makes the build fail since it happens in both.

2) Bug in JVM - buffer overflow.

That's the issue.

[I should have mentioned that I had also read the job log,
before posting.]

Both of these could happen with any Java version.

Or is this a hint for making Java 8 the minimum supported

version for the next release?

That is not a valid conclusion from the evidence.

How do you draw that conclusion?

More to the point, my request is: What to do to fix the negative
advertisement for the project which this Travis issue propagates
