> camel-cxf - CxfSpringEndpoint shuts down the shared application-wide CXF bus
> on endpoint stop
> ---------------------------------------------------------------------------------------------
>
> Key: CAMEL-24181
> URL: https://issues.apache.org/jira/browse/CAMEL-24181
> Project: Camel
> Issue Type: Bug
> Components: camel-cxf
> Reporter: Federico Mariani
> Assignee: Claus Ibsen
> Priority: Major
>
> *Severity:* High
> h3. Problem
> {{CxfSpringEndpoint.setApplicationContext}} does:
> {code:java}
> if (bus == null) {
> createBus = true;
> bus = BusWiringBeanFactoryPostProcessor.addDefaultBus(ctx);
> }
> {code}
> {{addDefaultBus}} returns the *context-wide singleton* bus bean {{"cxf"}} -
> creating it only if absent, otherwise returning the user's own bus
> ({{<cxf:bus>}}, imported {{cxf.xml}}). Setting {{createBus = true}} marks
> this shared bus as endpoint-owned, so the inherited {{CxfEndpoint.doStop()}}
> runs {{getBus().shutdown(false)}} on it. Every {{<cxf:cxfEndpoint>}} bean
> (prototype scope) shares the one {{"cxf"}} bus.
> h3. Impact
> In a Spring context with more than one route using {{<cxf:cxfEndpoint>}} (or
> a Camel route plus a non-Camel CXF {{<jaxws:endpoint>}} on the default bus),
> removing/stopping one route while the application keeps running shuts down
> the *application-wide* bus - every other CXF server/client on that bus stops
> responding. Worse variant: the user explicitly configured {{<cxf:bus>}};
> Camel still sets {{createBus=true}} and destroys a user-managed bean.
> h3. Location
> {{components/camel-cxf/camel-cxf-spring-soap/src/main/java/org/apache/camel/component/cxf/spring/jaxws/CxfSpringEndpoint.java}}
> ~272-279, with {{CxfEndpoint.doStop()}}. Introduced by CAMEL-12829 (added
> {{createBus = true}} to fix a leak, without considering the
> shared/user-supplied bus case).
> h3. Fix
> Do not set {{createBus = true}} when the bus came from / already existed in
> the application context - its lifecycle belongs to Spring ({{SpringBus}}
> shuts itself down on {{ContextClosedEvent}}). Only claim ownership of a
> genuinely auto-created bus (when {{ctx.containsBean("cxf")}} was false) and
> shut it down on ApplicationContext close, not endpoint stop.
