Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of WebSphere Liberty deploying OSGi   *
  *                  applications.                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: An OSGi application bundle might not    *
  *                      start if it has a header "Bundle-       *
  *                      RequiredExecutionEnvironment" with a    *
  *                      JavaSE-9 or higher.                     *
  ****************************************************************
  * RECOMMENDATION:  The Bundle-RequiredExecutionEnvironment     *
  *                  header was deprecated in version 4.3 of the *
  *                  OSGi specification.                         *
  *                  For new development use the "Require-       *
  *                  Capability" header. E.g. "Require-          *
  *                  Capability: osgi.ee;filter:="(&             *
  *                  (osgi.ee=JavaSE)(version=17))"              *
  *                  If the application bundle manifest headers  *
  *                  cannot be modified, install this APAR to    *
  *                  address the issue.                          *
  ****************************************************************
  In an OSGi application bundle the OSGi bundle manifest header
  Bundle-RequiredExecutionEnvironment with a JavaSE-9 or greater
  may result in an error.
  For example:
  ...missing requirement
  org.apache.aries.subsystem.core.archive.OsgiExecutionEnvironment
  Requirement: namespace=osgi.ee, attributes={},
  directives={filter=(osgi.ee=JavaSE-17)}
