I have been able to replicate this bug. It becomes apparent when attempting to run Minecraft.jar, the official Minecraft Java client under OpenJDK 9 on a fresh install of Ubuntu Mate 18.04 Beta 2. https://i.imgur.com/HRzRl8J.png
I was able to find a solution though it isn't a proper fix. Purge all related packages and install the older openjdk-8-jre first, then an newer version on top of it. It looks like the default packages are not installing the certificates properly. See https://askubuntu.com/questions/971059/17-10-openjdk-and-oracle- jdk-8-and-9-the-trustanchors-parameter-must-be-non-empt under amb85. Ubuntu MATE 18.04 includes a ppa in the Software Boutique which installs Minecraft, but it runs into the same issue as using Minecraft.jar from Mojang's website. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743139 Title: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-9/+bug/1743139/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
