Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - The WebSphere MQ V7.1 classes for Java.
  - The WebSphere MQ V7.1 classes for JMS.
  - The WebSphere MQ V7.1 Resource Adapter.
  - The WebSphere Application Server V7.1 WebSphere MQ messaging
    provider.
  - The WebSphere Application Server V6.1 WebSphere MQ messaging
    provider who have configured the WebSphere variable
    MQ_INSTALL_ROOT to point to a WebSphere MQ V7 installation.
  
  with an application that utilises the Apache Axis2 client.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A WebSphere MQ classes for JMS or classes for Java application
  that embedded the Apache Axis2 client attempted to load the
  com.ibm.mq.ese.jmqi.ESEJMQI class for WebSphere MQ Advanced
  Message Security in the following process:
  
  org.apache.axis2.deployment.DeploymentClassLoader.findClass()
  
  If this class could not be found then the Apache Axis2
  classloader threw a java.lang.RuntimeException with a nested
  java.lang.ClassNotFoundException.
  
  The WebSphere MQ classes for JMS and classes for Java expected a
  java.lang.ClassNotFoundException to be thrown if the class could
  not be found, but did not handle the case where this exception
  was instead a linked exception within a
  java.lang.RuntimeException wrapper. As a result, a connection to
  a WebSphere MQ queue manager was not established and the
  exception thrown back to the application or JEE container.
  

Problem conclusion

• The WebSphere MQ classes for JMS and classes for Java have been
  updated to catch a java.lang.RuntimeException where the cause is
  a nested java.lang.ClassNotFoundException exception resulting
  from a failure to load the class com.ibm.mq.ese.jmqi.ESEJMQI
  class. java.lang.RuntimeException exceptions that do not have a
  java.lang.ClassNotFoundException exception as the cause are not
  caught and continue to be thrown to the application or
  container.
