PI60749: Common shared library classes return null when calling getProtec tionDomain().getCodeSource().getLocation()

Fixes are available

APAR status

Closed as program error.

Error description

Classes loaded from a Liberty server's common shared library
classloader use a ProtectionDomain that returns a null code
source location.  Some applications and third-party
libraries depend on that location being accurate so that it
can load additional resources from that class's archive
independent of the application server's classloading or
resource loading mechanisms.  When the code source location
is incorrect, these applications or libraries fail to
function correctly.

It may be possible to work around this problem by specifying
a non-null code source in a javaPermission element in the
server's configuration XML (server.xml, etc.).

Problem conclusion

The fix for this APAR is to provide a more accurate code source
location when defining the class from the common shared
library's classloader.

The fix for this APAR is currently targeted for inclusion in fix
pack 16.0.0.2.  Please refer to the Recommended Updates page for
