             Summary: Misconfiguration in Tomcat https configuration / UpgradeHandler
                 Key: OFBIZ-11408
                 URL: https://issues.apache.org/jira/browse/OFBIZ-11408
             Project: OFBiz
          Issue Type: Bug
          Components: framework
    Affects Versions: Trunk
            Reporter: Michael Brohl
            Assignee: Michael Brohl


During startup the following error message is displayed while initializing the Tomcat https connector:
{code:java}
Feb 23, 2020 12:21:39 PM org.apache.coyote.http11.AbstractHttp11Protocol configureUpgradeProtocol
SEVERE: The upgrade handler [org.apache.coyote.http2.Http2Protocol] for [h2] only supports upgrade via ALPN but has been configured for the ["https-jsse-nio-8443"] connector that does not support ALPN.
Feb 23, 2020 12:21:39 PM org.apache.coyote.AbstractProtocol init
INFO: Initializing ProtocolHandler ["https-jsse-nio-8443"]{code}
This is because ALPN is not supported in Java 8 (Java 9 and above). It needs some additional configuration.

As far as I see, this affects the protocol upgrade which fails, https is working ok though.

This affects trunk, have to check 17.12/18.12.
