java.lang.NoClassDefFoundError: org/apache/synapse/task/Task when deploying custom task

I deployed a simple custom task placing it in lib/endorsed. At startup, synapse find the class with my custom task alright but it cannot find it's own Task interface. The Task interface is defined in synapse-tasks-2.1.0.jar and I verified the jar is included in synapse classpath.
My custom task:
package com.mytest.synapse;

import org.apache.synapse.task.Task;

public class MyTask implements Task {

  @Override
  public void execute() {
    System.out.println("my task in action");
  }
}


Synapse config file:

<definitions xmlns="http://ws.apache.org/ns/synapse">
    <task class="com.mytest.synapse.MyTask" name="Task1">
        <trigger interval="5"/>
    </task>
</definitions>

 Have you tried placing your jar in the lib directory instead of lib/endorsed? We typically don't use the endorsed directory to place custom code.

Thanks,
