JR44011: CMVC 224288 - TO HANDLE THE CONTENT PARSING EXCEPTION WHEN THE WC_USERACTIVITY COOKIE IS INCOMPLETE IN THE USER REQUEST

WebSphere Commerce Version 7.0.0.7 Fix Pack

APAR status

• Closed as program error.

Error description

• When the content of WC_USERACTICITY cookie is incomplete, error
  happens during cookie parsing phase. However, the exception is
  not handled correctly, and then a blank page is returned with
  200 status code. Since the 200 blank page will be cached for a
  period of time, making this blank page much more visible to
  other Shoppers.
  There is an exception in the trace file:
  [8/22/12 22:05:02:448 CST] 0000135b CommerceSrvr E
  com.ibm.commerce.webcontroller.WebControllerHelper

  g,ServletContext,Integer) CMN0409E: The following error occurred
  during processing: "java.lang.StringIndexOutOfBoundsException".

Local fix

  eId, catch StringIndexOutOfBoundsException and throw
