Hello,

after we updated our jenkins installation from 2.214 to 2.217 today we encountered a serious problem with the updated winstone-jetty:

SEVERE: 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

There is only one certificate in our jenkins keystore, wich is a JKS based keystore. It seems to be connected to the jetty-9.4.23 update (Releasenotes entry: 4325 Deprecate SniX509ExtendedKeyManager constructor without SslContextFactory$Server)

Jenkins startup was aborted.

After a downgrade to jenkins 2.214 everything was fine again.

Best regards,

Heiko
