Local fix

• The only available workaround is to remove the Compuware
  dynaTrace agent from the Tomcat server.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Administrators of a Worklight server who use Tomcat as their *
  * server runtime using the DynaTrace agent                     *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * The Dynatrace agent loads websphere classes that are not     *
  * used on tomcat servers, causing class not found exceptions   *
  * to occur when using this agent on their tomcat server        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *
  ****************************************************************
  

Problem conclusion

• The code that uses the websphere APIs that are normally
  statically loaded are now dynamically loaded on demand when
  using a websphere server.
