Build job is killed with Java result returning 137

I am looking at a build job that ran today:
https://travis-ci.org/Jasig/cas/builds/71857300

My build matrix is comprised of OracleJdk7, 8 and OpenJdk7. For some reason, the build jobs that are for OpenJdk7 and OracleJdk8 fail with the following error message:

What could kill the process? and why could this happen for those two options and not OracleJdk7?

Could be memory issue, see: #4192
