  * PROBLEM DESCRIPTION: The server unexpectedly emits           *
  *                      warrning message WSVR0320W.             *

  ****************************************************************
  The server unexpectedly emits warning message WSVR0320W
  indicating it will override the classloader delegation mode
  for a Web module, e.g. "MyWebModule.war":
  [7/16/18 5:27:11:652 EDT] 0000004d DeployedModul W
  WSVR0320W: The deployed object classloading mode, PARENT-LAST,
  will override the deprecated module deployment classloading
  mode, PARENT-FIRST, of the web module deployment,
  WyWebModule.war.
  The warning is unexpected, and also benign, because the
  classloader mode in the web module deployment appears
  configured for PARENT_LAST delegation. Here is a snippet of a
  web module deployment (deployment.xml) that causes the server
  to emit the unexpected warning. Notice the configuration
  declares a classloader element with attribute "mode" set to
  "PARENT-LAST", but lacks the deprecated classloaderMode
  attribute.
  <deployedObject
  xmi:type="appdeployment:ApplicationDeployment"
  xmi:id="ApplicationDeployment_1234567890123"
  ...>
  ...
  <modules
  xmi:type="appdeployment:WebModuleDeployment"
  xmi:id="WebModuleDeployment_1234567890123"
  uri="MyWebModule.war"
  ...>
  ...
  <classloader xmi:id="Classloader_1234567890123"
  mode="PARENT_LAST"/>
  </modules>
  ...
  The server should not emit message WSVR0320W when the
  classloaderMode attribute is not set.
  Here is a snippet of the same web module deployment for which
  the server must emit the warning shown above. Notice the
  classloaderMode attibute is set, and its value (PARENT_FIRST)
  differs from the classloader mode setting (PARENT_LAST).
  <deployedObject
  xmi:type="appdeployment:ApplicationDeployment"
  xmi:id="ApplicationDeployment_1234567890123"
  ...>
  ...
  <modules
  xmi:type="appdeployment:WebModuleDeployment"
  xmi:id="WebModuleDeployment_1234567890123"
  uri="MyWebModule.war"
  classloaderMode="PARENT-FIRST"
  ...>
  ...
  <classloader xmi:id="Classloader_1234567890123"
  mode="PARENT_LAST"/>
  </modules>
  ...
  The server will override the deprecated classloaderMode
  setting for a web module deployment whenever the
  classloadMode (deprecated) and classloader mode attributes
  are set to different values.
  

Problem conclusion

• Apply APAR PI88219 to ensure the application server emits
  message WSVR0320W for a web module deployment only when
  the classloadMode and classloader mode attributes are set to
  different values within the application's deployment.xml file.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs and 8.5.5.15 and 9.0.0.11.  Please refer to the
