The problem should be due to that the newer version of java 1.8 disables some of the weak ciphers/algorithm. The Signature Algorithm of the certificate used by problem rvrd is MD5withRSA, which is disabled by JRE 1.8.0u92.
If you download the latest the JDK 1.8. You should be able to reproduce the problem.
