APAR status

• Closed as program error.

Error description

• Abstract: Annotation scans will emit warning messages for class
  references which do not resolve.  In many cases, the failure to
  resolve the class reference is harmless, and the warning should
  not be displayed.
  
  For example:
  
  com.ibm.ws.amm.scan.context.ScannerContextImpl
  getInputDataForClass
  Failed to open resource
  org/apache/struts2/views/jsp/ui/ActionErrorTag.class

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: A setting is needed to prevent          *
  *                      warnings for unresolvable classes       *
  *                      which are processed while scanning      *
  *                      annotations.                            *

  * RECOMMENDATION:                                              *
  ****************************************************************
  Annotation scans must process class references for all classes
  of applications.  Scans are performed when deploying
  applications, and while starting applications.
  The annotation scans will emit warning messages for class
  references which do not resolve.  Warnings similar to the
  following will be emitted to server logs:
  [17/04/06 9:46:59:211 JST] 000000b7 annotations   W
  com.ibm.ws.amm.scan.context.ScannerContextImpl
  getInputDataForClass
  Failed to open resource [
  org/apache/struts2/views/jsp/ui/ActionErrorTag.class ] from
  module [ <module_name>.war ]
  In many cases, the warning indicates that classes are missing
  from the application, which is a serious problem.  In other
  cases, the class reference occurs in code which is not used by
  the application, and the failure to resolve the reference is
  harmless.  When the failure to resolve the class reference is
  harmless, having the warning not be emitted is desirable.
  

Problem conclusion

• A new setting is added which prevents the warning message
  from being displayed.
  
  The setting may be set as a JVM custom property, as a property
  in the "amm.filter.properties" property file, or as a manifest
  attribute in application and module archive files.  Setting
  a JVM custom property enables the setting for
  a single Java process.  Setting the property in
  "amm.filter.properties" enables the setting for all processes.
   Setting a main attribute in a manifest file enables the
  setting in the scope of the archive holding the manifest.
  (Setting an attribute in the application manifest enables the
  setting for all modules of the application.  Setting an
  attribute in a module manifest enables the setting for just
  that module.)
  
  To enable the setting as a JVM custom property, add this
  custom property:
  
  com.ibm.ws.amm.reduce.warning.messages=true
  
  To enable the setting as a property in
  "amm.filter.properties", add this property to the
  properties file:
  
  Reduce-AMM-Warning-Messages=true
  
  To enable the setting as a property in a manifest file, add
  the following main attribute to the target application
  archive or module archive:
  
  Reduce-AMM-Warning-Messages: true
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.13 and 9.0.0.5.  Please refer to the Recommended
