Camel和Quartz2和某些机器的奇怪故障

Question

I have a WAR file with the following Camel Route:

qtz.expression read from property file and set value as: 0/30+*+*+*+*+?

    from("quartz2://schedulerVigenciaClienteEnvase?cron={{qtz.expression}}")
            .handleFault()
            .log("Testing job")
            .process("testProcessor");

It uses Camel 2.20, and Camel Quartz2. The following are the dependencies inside the POM file.

<dependencies>
    <!-- ${camel.version} contains 2.20.2 value -->
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-core</artifactId>
       <version>${camel.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-spring</artifactId>
      <version>${camel.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-servlet</artifactId>
      <version>${camel.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-quartz2</artifactId>    
      <version>${camel.version}</version>   
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-jms</artifactId>
        <version>${camel.version}</version>
    </dependency>  
</dependencies>

The trouble is in some machines using the same Java version produces the following exception each Quartz triggering moment.

2018-03-22 18:54:00,005 JobRunShell ERROR Job Camel_camel-1.schedulerVigenciaClienteEnvase threw an unhandled Exception:

java.lang.NoSuchMethodError: org.apache.camel.impl.DefaultMessage.(Lorg/apache/camel/CamelContext;)V

Why the method are not complaining in all the machines, using same JVM version and OS.

Any suggestions are appreciated.

Found the problem and the solution, in the project we are using ActiveMQ, so, there was a dependency called activemq-all , that inside includes an internal Camel implementation that collides at classloading (sometimes, not always). Final solution was replacing this dependency with the following list:

<!-- Apache Active MQ Jars -->
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-broker</artifactId>
        <version>${activemq.version}</version>     
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-client</artifactId>
        <version>${activemq.version}</version>     
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-pool</artifactId>
        <version>${activemq.version}</version>      
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-camel</artifactId>
        <version>${activemq.version}</version>      
    </dependency>
