WSO2 ESB - java.lang.ClassNotFoundException: org.apache.synapse.core.axis2.Axis2MessageContext

Question

I am having a mediator that receives a message, which is generated by VFS poller. I am trying to figure out the file name so that act on it differently. The code that pulls the fileName works, but sometimes I am getting ClassNotFoundException (see below). I gave to restart WSO2 one or more times in order for the class to be loaded successfully. I am running WSO2 ESB 4.8.0 on Ubuntu 12.04 with 8GB RAM and 4GB max Java Heap. Thanks, Krassimir

public boolean mediate(MessageContext context) {
...
String fileName = ((Map) ((Axis2MessageContext) context).getAxis2MessageContext()
        .getProperty("TRANSPORT_HEADERS")).get("FILE_NAME").toString();
...
