| Immediately after attempting to upgrade Jenkins automatically, Jenkins Windows service starts but fails within 4 seconds. See attached error log. The key error is apparently: java.lang.IllegalStateException: KeyStores with multiple certificates are not supported on the base class org.eclipse.jetty.util.ssl.SslContextFactory. (Use org.eclipse.jetty.util.ssl.SslContextFactory$Server or org.eclipse.jetty.util.ssl.SslContextFactory$Client instead) The issue relates to a change in Jetty noted at the following post: https://github.com/eclipse/jetty.project/issues/4425 Note that Jetty in Jenkins 2.217 was recently updated, per the changelog, from 9.4.22.v20191022 to 9.4.25.v20191220 Apparently a code fix is required to use the newer Jetty, as detailed in comment https://github.com/eclipse/jetty.project/issues/4425#issuecomment-565967384 |
