APAR status

• Closed as program error.

Error description

• The classloader for the resource adapter is not working
  correctly and is returning null for any Class.getPackage().
  
  When a resource adapter is installed on WebSphere Application
  Server, and inside this resource adapter classes (loaded using
  resource adapter classloader), if you have a code
  SomeClass.class.getPackage().getName(), it will crash in
  NullPointerException because getPackage() will return null.

  When installing a resource adapter, a NullPointerException
  will occur if resource adapter code attempts to use a
  package object for a resource adapter or resource adapter
  related class.

  This specific case occured from JBOSS logging code.  The JBOSS
  code is attempting to retrieve a fully qualified package
  name for a class loaded in relationship to a resource adapter
  class.
  In this specific case, the preferred alternative solution is to
  modify the JBOSS logging code to obtain the fully qualified
  package name directly from the fully qualified class name.  Use
  of a package object is unnecessary for obtaining the package
  name of a loaded class.
  

Problem conclusion

• A code update was made, including a new enablement custom
  property.  The code update, when enabled, causes package
  objects to be created when loading application classes.  This
  ensures that a non-null package is available for any loaded
  class.
  
  The new custom property is "com.ibm.ws.wtp.package.loads".
  This new custom property must be set to "true" in the failing
  process to enable the new code.  For simplicity, the new custom
  property can be safely set on all application server and
  deployment manager nodes.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.5.5.15 and 9.0.0.10.  Please refer to the
