Seems like a bug
Here is a full dependencyManagement and dependencies parts of pom.xml made
according to https://camel.apache.org/camel-spring-boot/latest/index.html
<dependencyManagement>
<dependencies>
<!-- Camel BOM -->
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-spring-boot-bom</artifactId>
<version>${camel-version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<!-- ... other BOMs or dependencies ... -->
</dependencies>
</dependencyManagement>
<dependencies>
<!-- Camel Starter -->
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
</dependency>
<!-- ... other dependencies ... -->
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-activemq-starter</artifactId>
</dependency>
</dependencies>
The main method looks like
@SpringBootApplication
@ImportResource("classpath:camel.xml")
public class MyApplication {
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}
Logs, where I have camel got started twice with 2 routes and 0 routes
respectively

The problem disappears if I remove ImportResource annotation, but how one could
set onException or InterceptFrom blocks in this case?

Тема: Re: migration to Camel 3.7
I figured out it is related to having camelContext described in camel.xml along
with another beans and for example camel-activemq-starter dependency in pom.xml
The one way to eliminate camelContext reloading is to drop camelContext
description at all, xml routes then could be placed in classpath directory to
be load. But I have interceptFrom, onException and others described in my
camelContext bean, where should I move it now?
Or, I noticed using the camel-activemq from org.apache.camel instead of
camel-activemq-starter from org.apache.camel.springboot also helps, would it be
correct?
Please, help

Тема: migration to Camel 3.7
Hi,
I have an issue when migrated from 3.5 to 3.7 Camel
According to logs there are 4 additional empty (0 routes) camel contexts being
started (camel-1 to camel-4)
Please tell if it is a feature and if so what is its purpose? Should I care
about these contexts or somehow treat them?
Camel 3.7.0, Spring Boot 2.4.1
Here is the logs, thanks in advance!
