Error importing gradle project

Having trouble importing an example gradle project into STS 3.6.1. However the same project imports without issue in STS 3.5.1.

Project is https://github.com/cf-platform-eng/spring-boot-cities. On the import dialog when pressing the 'build model' button, error appears: org.eclipse.osgi.internal.framework.EquinoxConfiguration$1 See error log for details.

Error log is:
