Error description
An OSGi application may contain bundles that register and use OSGi services with an objectClass contained in an API package. For example, javax.servlet.Servlet. The Liberty runtime may also contain bundles that register OSGi services using the same objectClass. Under certain circumstances it is possible for the OSGi application to get access to the OSGi services registered by Liberty runtime feature bundles whose objectClasses are from API packages but the services themselves are not considered APIs.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty Profile * **************************************************************** * PROBLEM DESCRIPTION: OSGi applications may be able to get * * access to OSGi services provided by * * Liberty feature bundles which are not * * considered API. * **************************************************************** * RECOMMENDATION: * **************************************************************** An OSGi application may contain bundles that register and use OSGi services with an objectClass contained in an API package. For example, javax.servlet.Servlet. The Liberty runtime may also contain bundles that register OSGi services using the same objectClass. Under certain circumstances it is possible for the OSGi application to get access to the OSGi services registered by Liberty runtime feature bundles whose objectClasses are from API packages but the services themselves are not considered APIs.
Problem conclusion
The Liberty feature header IBM-API-Service is used to specify which services are to be considered API services for use by OSGi applications. In past releases this header did not strictly enforce access to service registrations. Now this header is used to strictly enforce which services an OSGi application has access to at runtime. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.9. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
None. Applications may be accessing OSGi services that are not considered API services. With this fix applications will no longer be able to access OSGi services that are not considered API services.
