Firefox 51 and the new NSS library versions arrived in Tumbleweed a few days ago. The Java example does not run in an up-to-date Tumbleweed anymore. So as far as I understand it, this will be resolved with updates for the OpenJDK packages? Java:Factory already has 1.8.0.121 [1] for 42.2 with this in the change log: > Require the exact version of mozilla-nss that the package was built against (bsc#1022053) [1] https://build.opensuse.org/package/show?project=Java%3AFactory&package=java-1_8_0-openjdk
