      Description

      I develop an application on camel.It's routing logic as follows:
      <route>
      <from uri="cxf:bean:routerEndpoint" />
      <try>
      <process ref="ipValidateProcessor" />
      <choice>
      <when>
      <!-- First predicate -->
      <el>${in.headers.IP_VALIDATE_RESULT == 'true'}</el>
      <to uri="cxf:bean:serviceEndpoint" />
      <process ref="responseProcessor" />
      </when>
      <otherwise>
      <process ref="invalidIPProcessor" />
      </otherwise>
      </choice>
      <catch>
      <exception>com.aspire.archtype.camel.exception.AppException</exception>
      <process ref="sreExceptionHandler"></process>
      </catch>
      </try>
      </route>

      I do a pressure testing on this application with LoadRunner.
      My test case is as follows:
      1. loadrunner send a reqeust
      2. server receive the request, and then forward it to IPValidateProcessor
      3. IPValidateProcessor set exchange.getIn().setHeader("IP_VALIDATE_RESULT", "true");
      4. do <to uri="cxf:bean:serviceEndpoint" />
      5. do <process ref="responseProcessor" />
      6. end

      I only want to test the <when> clause in the routing logic.
      When only one virtual user runs the test case once, it runs ok.
      But when have 30 virtual users concurrent run for 1 minute, some of the transactions run into <otherwise> clause.I found that they run into <otherwise> because in.headers.IP_VALIDATE_RESULT is null.

      I don't now why, the same requests, most run into <when> clause, few run into <otherwith> clause?
