APAR status

  • Closed as program error.

Error description

  • In a Worklight adapter you can use a convenient XML E4X notation
    to build XML. For example:
    function login(username, password){
    var requestBody = <login>
    <username>{username}</username>
    <password>{password}</password>
    </login> ;
    
    However doing so and running the server under load shows that
    the CPU is unable to increase more than 30% and a thread dump
    shows blocked threads in XmlProcessor.
    

Local fix

  • Use Strings to concatenate XML objects.

    * PROBLEM DESCRIPTION:                                         *
    * Under load, the current usage of a third party library leads *
    * to contention issues.                                        *
    ****************************************************************
    * RECOMMENDATION:                                              *

Problem conclusion

  • The code has been modified to work around the contention issues.
    
    The fix for this APAR is currently targeted for inclusion in
