David Handermann updated NIFI-12539:
------------------------------------
Affects Version/s: (was: 2.0.0)
> Nifi Registry not accept connection in secure mode
> --------------------------------------------------
>
> Key: NIFI-12539
> URL: https://issues.apache.org/jira/browse/NIFI-12539
> Project: Apache NiFi
> Issue Type: Bug
> Components: NiFi Registry
> Reporter: Zoltán Kornél Török
> Priority: Critical
>
> h3. Problem description
> When you configure nifi-registry to be secure and try to connect to it via
> [https://127.0.0.1:18443/nifi-registry] it will throw the following
> exceptions in the log (and not load the ui and also api calls not works):
> {code:java}
> 2023-12-22 10:48:14,340 WARN [NiFi Registry Web Server-46]
> org.eclipse.jetty.io.ManagedSelector Could not accept
> java.nio.channels.SocketChannel[closed]: java.lang.NoClassDefFoundError:
> org/eclipse/jetty/io/ssl/SslConnection$DecryptedEndPoint {code}
> h3. What cause the problem?
> The problem exists since
> [https://issues.apache.org/jira/projects/NIFI/issues/NIFI-12434] is merged.
> In that ticket the spring version is increased and also the Jetty from
> 11.0.18 to 12.0.3. That cause the problem, because in case of nifi the jetty
> version remained 11.0.18 and there is a code which use
> {color:#000000}SslConnection{color}.{color:#000000}DecryptedEndPoint{color}
> class:
> [https://github.com/apache/nifi/blob/main/nifi-commons/nifi-jetty-configuration/src/main/java/org/apache/nifi/jetty/configuration/connector/alpn/StandardALPNProcessor.java#L62]
> In case of nifi this is working fine, but the same maven module used in
> nifi-registry as well and in Jetty 12.0.3 the
> {color:#000000}SslConnection{color}.{color:#000000}DecryptedEndPoint{color}
> class is removed, that is why we got the NoClassDefFoundError and see this.
> h3. Possible solutions?
> * increase jetty version in nifi and refactor code to support new version
> * Duplicate code for nifi-registry and modify for it (not recommended as
> code duplication later could cause trouble)
> * Revert back code change (not recommended as sooner / later definitly need
> to increase versions)
