On Mac and Windows, update your JDK from Oracle, for sure java full version "1.8.0_131-XXX" works on the Mac and Windows. Mac and Windows versions of the JDK generally do not use the system certificate stores instead they have their own.

For Linux, apt-get ca-certificates which will in turn update the Java certificates if you had the ca-certificates-java installed.

The new certificates will work with repository.primefaces.org
