Public bug reported: My original problem was that leiningen was not able to download a project's dependencies, instead it gave errors containing "java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty"
I have verified this with a minimal Java program (attached) Expected behaviour: reads and prints the first line of the Leiningen README from github (nothing significant about this file except that it is accessible via https) Actual behaviour: error report (attached, first few line reproduced below) Exception in thread "main" javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/sun.security.ssl.Alerts.getSSLException(Alerts.java:214) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1974) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1926) I have checked that I get the expected behaviour on Windows ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: openjdk-11-jdk 10.0.1+10-3ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-20.21-generic 4.15.17 Uname: Linux 4.15.0-20-generic x86_64 ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 CurrentDesktop: LXDE Date: Thu May 3 11:14:28 2018 InstallationDate: Installed on 2018-04-03 (29 days ago) InstallationMedia: Lubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) SourcePackage: openjdk-lts UpgradeStatus: Upgraded to bionic on 2018-04-27 (5 days ago) ** Affects: openjdk-lts (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic ** Attachment added: "Example Java file" https://bugs.launchpad.net/bugs/1768799/+attachment/5132892/+files/JavaApplication92.java -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768799 Title: Java can't connect to https sites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-lts/+bug/1768799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
