-------------------------------------
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.
