Hello The thread names in your log output explain the "problem". First the feature service starts Jetty server, but later, Configuration Admin updates `org.apache.felix.http` PID and CM's ManagedService from Felix restarts the server based on non-default configuration.
Usually this "problem" (actually it's an OSGi dynamism in action) is avoided with options like "waitForConfigurationAdmin", where the Activator does not start its service if the configuration does not come from ConfigurationAdmin. We do it in Pax URL Aether and Pax Web too. I'm not sure if such option is configuration in Felix HTTP. kind regards Grzegorz Grzybek pt., 5 cze 2026 o 22:29 Martin Lichtin via user <[email protected]> napisał(a): > Hi > > when loading Felix Jetty12, i.e. using bundles > <bundle>mvn:org.apache.felix/org.apache.felix.http.servlet-api/6.1.0</bundle> > <bundle>mvn:org.apache.felix/org.apache.felix.http.jetty12/1.1.10</bundle> > > I'm seeing a weird startup behaviour. > First Jetty comes up on its default port, then immediately it stops and > restarts on the configured port. > > 2026-06-05T22:12:47,160 | INFO | features-3-thread-1 | Server > | org.eclipse.jetty.server.Server 555 | jetty12 - 1.1.10 > | jetty-12.0.35; built: 2026-05-01T05:38:52.785Z; git: > ae9286497b46fd709861e330fb364408a946d6e5; jvm 21.0.7+8-LTS-245 > 2026-06-05T22:12:47,214 | INFO | features-3-thread-1 | > DefaultSessionIdManager | .session.DefaultSessionIdManager 328 | jetty12 - > 1.1.10 | Session workerName=node0 > 2026-06-05T22:12:47,263 | INFO | features-3-thread-1 | > ContextHandler | ty.server.handler.ContextHandler 795 | jetty12 - > 1.1.10 | Started oeje10s.ServletContextHandler@5ceabbe > {ROOT,/,b=null,a=AVAILABLE,h=oeje10s.SessionHandler@7b853b1e{STARTED}} > 2026-06-05T22:12:47,266 | INFO | features-3-thread-1 | > ServletContextHandler | 10.servlet.ServletContextHandler 1056 | jetty12 - > 1.1.10 | Started oeje10s.ServletContextHandler@5ceabbe > {ROOT,/,b=null,a=AVAILABLE,h=oeje10s.SessionHandler@7b853b1e{STARTED}} > 2026-06-05T22:12:47,272 | INFO | features-3-thread-1 | Server > | org.eclipse.jetty.server.Server 612 | jetty12 - 1.1.10 > | Started oejs.Server@36bd8b51{STARTING}[12.0.35,sto=0] @87943ms > 2026-06-05T22:12:47,363 | INFO | features-3-thread-1 | > AbstractConnector | e.jetty.server.AbstractConnector 326 | jetty12 - > 1.1.10 | Started ServerConnector@43bd20cc{HTTP/1.1, (http/1.1)}{ > 0.0.0.0:8080} > 2026-06-05T22:12:47,366 | INFO | features-3-thread-1 | http > | http.jetty.internal.JettyService 455 | jetty12 - 1.1.10 > | Started Jetty 12.0.35 at port(s) HTTP:8080 on context path / > [minThreads=8,maxThreads=200,acceptors=1,selectors=6,virtualThreadsEnabled=false] > 2026-06-05T22:12:47,612 | INFO | : pid=[org.apache.felix.http]) | Server > | org.eclipse.jetty.server.Server 652 | jetty12 - 1.1.10 > | Stopped oejs.Server@36bd8b51{STOPPING}[12.0.35,sto=0] > 2026-06-05T22:12:47,618 | INFO | : pid=[org.apache.felix.http]) | > AbstractConnector | e.jetty.server.AbstractConnector 381 | jetty12 - > 1.1.10 | Stopped ServerConnector@43bd20cc{HTTP/1.1, (http/1.1)}{ > 0.0.0.0:8080} > 2026-06-05T22:12:47,624 | INFO | : pid=[org.apache.felix.http]) | > ServletContextHandler | 10.servlet.ServletContextHandler 1118 | jetty12 - > 1.1.10 | Stopped oeje10s.ServletContextHandler@5ceabbe > {ROOT,/,b=null,a=AVAILABLE,h=oeje10s.SessionHandler@7b853b1e{STOPPED}} > 2026-06-05T22:12:47,627 | INFO | : pid=[org.apache.felix.http]) | http > | http.jetty.internal.JettyService 275 | jetty12 - 1.1.10 > | Stopped Jetty > 2026-06-05T22:12:47,629 | INFO | : pid=[org.apache.felix.http]) | Server > | org.eclipse.jetty.server.Server 555 | jetty12 - 1.1.10 > | jetty-12.0.35; built: 2026-05-01T05:38:52.785Z; git: > ae9286497b46fd709861e330fb364408a946d6e5; jvm 21.0.7+8-LTS-245 > 2026-06-05T22:12:47,631 | INFO | : pid=[org.apache.felix.http]) | > DefaultSessionIdManager | .session.DefaultSessionIdManager 328 | jetty12 - > 1.1.10 | Session workerName=node0 > 2026-06-05T22:12:47,632 | INFO | : pid=[org.apache.felix.http]) | > ContextHandler | ty.server.handler.ContextHandler 795 | jetty12 - > 1.1.10 | Started oeje10s.ServletContextHandler@21abe183 > {ROOT,/,b=null,a=AVAILABLE,h=oeje10s.SessionHandler@248f5f41{STARTED}} > 2026-06-05T22:12:47,633 | INFO | : pid=[org.apache.felix.http]) | > ServletContextHandler | 10.servlet.ServletContextHandler 1056 | jetty12 - > 1.1.10 | Started oeje10s.ServletContextHandler@21abe183 > {ROOT,/,b=null,a=AVAILABLE,h=oeje10s.SessionHandler@248f5f41{STARTED}} > 2026-06-05T22:12:47,633 | INFO | : pid=[org.apache.felix.http]) | Server > | org.eclipse.jetty.server.Server 612 | jetty12 - 1.1.10 > | Started oejs.Server@f7ae73d{STARTING}[12.0.35,sto=0] @88304ms > 2026-06-05T22:12:47,660 | INFO | : pid=[org.apache.felix.http]) | > AbstractConnector | e.jetty.server.AbstractConnector 326 | jetty12 - > 1.1.10 | Started ServerConnector@a4f7439{HTTP/1.1, (http/1.1)}{ > 0.0.0.0:8188} > 2026-06-05T22:12:47,661 | INFO | : pid=[org.apache.felix.http]) | http > | http.jetty.internal.JettyService 455 | jetty12 - 1.1.10 > | Started Jetty 12.0.35 at port(s) HTTP:8188 on context path / > [minThreads=8,maxThreads=200,acceptors=1,selectors=6,virtualThreadsEnabled=false] > > Anyone understands why this occurs, and how it can be avoided? > > - Martin > > Karaf 4.4.11 >
