If your problem is related to that link, then you should have tried to
downgrade the JDK, and it should have worked. To double check you can
check the
/usr/lib/jvm/java-1.7.0-openjdk-*/jre/lib/security/java.security file.
It may contain this line, at the very end:

  jdk.tls.disabledAlgorithms=SSLv3

That is because of the recent security problems with SSLv3. If you need
to solve your problem urgently and you are sure that you won't be
affected by those security problems then you can just comment out this
line and restart the engine.

Remember to undo this change once you upgrade to 3.5.
