IT33606: STRINGINDEXOUTOFBOUNDSEXCEPTION IN INTEGRATION NODE LEVEL LISTENER IF HTTP HEADER CONTAINS TRAILING SLASH AND NO VALUE

APAR status

• Closed as program error.

Error description

• If the Integration Node level HTTP listener receives an HTTP
  header which has a trailing slash in its name and no value then
  the following exception message is appended to the response
  body:
  
  java.lang.StringIndexOutOfBoundsException
  
  java.lang.String.charAt(String.java:1368)
   com.ibm.broker.httpli
  stener.ServletFunctions.recapitaliseHeader(ServletFunctions.java
  :150)
   com.ibm.broker.httplistener.ServletFunctions.process(Serv
  letFunctions.java:327)
   com.ibm.broker.httpservlet.WMQIServlet.d
  oGet(WMQIServlet.java:92)
  
  javax.servlet.http.HttpServlet.service(HttpServlet.java:624)
   co
  m.ibm.broker.httpservlet.WMQIServlet.service(WMQIServlet.java:19
  1)
   javax.servlet.http.HttpServlet.service(HttpServlet.java:731)
  
  
  The failure is caused by an error during the recapitalising
  of HTTP headers. The header should be recapitalised and passed
  to the flow.
