Is there any specific reason why this is happening or what and where i should look as i am really clueless as to why change in camel results in spring's class not being found?
And apart from this, all my routes made in java configuration are not working and throw exceptions like consumer not found for endpoint for all the routes that consume message from given endpoint but same seems to work in when writen in xml. Is there any reason for this? I am using camel 2.13.2 and java configuration for routes is done by extending RouteBuilder, also i have other routes that are already written in xml and the xml has been added in contextConfigLocation. Is it somehow related to adding xml in contextConfig?
camel-jms:2.18.1 component uses spring-jms with version 4.3.4.RELEASE. You need to upgrade to spring 4.3.4.RELEASE or migrate camel-jms component to camel-sjms, which does not use spring. You can find all relevant dependencies in camel-parent-2.18.1.pom
If you are using Maven, the best way to keep your dependencies consistent is using BOM:
<dependencyManagement>
<dependnecies>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-parent</artifactId>
<version>2.18.1</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependnecies>
</dependencyManagement>
and then exclude version for all camel and spring related dependencies, which you are using in application.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
</dependency>
...
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
</dependency>
