Error description

• Please refer to internal CMVC defect 211118
  
  Managing Server: ITCAM for AD 7.1
  Data Collector: ITCAM for AD 7.1
  
  Environment Details:
  
  OS Information: Windows
  AppServer: WAS 6.1
  J2EE Application: Axis 1.4.x
  
  Steps to reproduce:
  
  The issue was uncovered when working on Axis1.4. Code segment
  below recreated the issue:
  
  try {
  
  CalculatorService service = new CalculatorServiceLocator();
  
  // get service
  Calculator calc = service.getCalculator();
  
  // create stub
  org.apache.axis.client.Stub s = (org.apache.axis.client.Stub)
  calc;
  
  // set timeout
  setTimeout(2000);  // 2 second, in milliseconds
  out.println("timeout is " + 2000 + " milliseconds");
  
  // invoke sleep operation with 5000 to trigger timeout and
  client side exception
  calc.sleep(5000);
  
  } catch (Exception e) {
  e.printStackTrace();
  out.println("Exception " + e);
  }
  
  LOCAL FIX:
  
  Comment out ws.instrument=true at
  DCHOME/runtime/node.server/datacollector.properties
  
  If ws.instrument=true is commented out or set to a value of
  false (ws.instrument=false), Web Service monitoring is disabled
  and stack corruption can be prevented.
  
  Code Fix:
  
  Refer to track 211118.
  AXIS 1.x callback should handle exception by AxisClient's
  invoke() method to prevent DC side stack corruption.
