  *                  Server V8.5.0 who make use of the wsdb2gen  *
  *                  command.                                    *
  ****************************************************************

  *                      NoClassDefFoundError indicating         *

  ****************************************************************
  A "java.lang.ClassNotFoundException:
  org.objectweb.asm.ClassVisitor" is reported when a class file
  is processed by the wsdb2gen command. This is caused by a
  incorrect definition of classpath in the command that is
  required to load the appropriate open source artifacts.
  

Problem conclusion

• With this fix, the missing open source artifacts in the
  wsdb2gen classpath has been resolved.
  
  The fix for this APAR is currently targeted for inclusion
  in 8.5.5.0.  Please refer to the Recommended Updates
  page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
