Claus Ibsen resolved CAMEL-23449.
---------------------------------
Resolution: Not A Bug
Camel 4.19 onwards is Spring Boot 4, and therefore Spring 7.x and so on.
> Camel Spring Xml >= 4.19.0 no longer works with Spring 6
> --------------------------------------------------------
>
> Key: CAMEL-23449
> URL: https://issues.apache.org/jira/browse/CAMEL-23449
> Project: Camel
> Issue Type: Bug
> Components: camel-spring-xml
> Affects Versions: 4.19.0, 4.20.0
> Reporter: Dr. Ernst-Udo Wallenborn
> Priority: Major
>
> With Spring version 6.2.18 and Camel 4.19.0 or newer, our application throws
> this at startup:
> {noformat}
> 2026-05-07 13:05:43,110 ERROR
> [(:)][org.springframework.web.context.ContextLoader] Context initialization
> failed
> java.lang.NoSuchMethodError:
> 'org.springframework.context.ApplicationContext
> org.springframework.context.event.ContextRefreshedEvent.getSource()'
> at
> org.apache.camel.spring.xml.CamelContextFactoryBean.onApplicationEvent(CamelContextFactoryBean.java:480)
> at
> org.apache.camel.spring.xml.CamelContextFactoryBean.onApplicationEvent(CamelContextFactoryBean.java:99)
> {noformat}
> The code in CamelContextFactoryBean is:
> {code:java}
> if (event.getSource() instanceof ApplicationContext) {
> ApplicationContext appCtx = (ApplicationContext)
> event.getSource();
> {code}
> and hasn't changed significantly since 4.18.2. But running
> camel-spring-xml-4.19.0.jar through the decompiler the code changes to:
> {code:java}
> if (event.getSource() instanceof ApplicationContext) {
> ApplicationContext appCtx = event.getSource();
> {code}
> where the typecast is removed. Apparently, Spring 7 implements getSource() in
> ApplicationContextEvent:
> {code:java}
> /**
> * Get the {@link ApplicationContext} that the event was raised for.
> * @return the {@code ApplicationContext} that the event was raised for
> * @since 7.0
> * @see #getApplicationContext()
> */
> @Override
> public ApplicationContext getSource() {
> return getApplicationContext();
> }
> {code}
> and this covariant override causes the compiler to remove the cast.
