PI57255: MyFaces CDI support is disabled if non-CDI application is loaded first

Fixes are available

APAR status

Closed as program error.

Error description

?If MyFaces 2.2 is loaded at the server level, MyFaces CDI
support is set once per server. This causes CDI-enabled JSF
applications to not work properly if a non-CDI application
is loaded first.

Steps to reproduce the error on WebSphere Liberty
1. Enable the jsf-2.2 and cdi-1.2 features on the WebSphere
Liberty server.
2. Deploy two JSF applications: one that uses CDI (for
example, a flow built using FlowBuilder) and one that does
not use CDI.
3. Make a request to the non-CDI application first. The
message 'MyFaces CDI support disabled' should be written to
the
      logs.
4. Make a request to the CDI-enabled application. If testing
an application with a flow built using FlowBuilder, the flow
      will not be discovered.

Investigation has found that MyFaces has two conditions to
determine CDI availability:
  1. CDI must be found on the classpath
  2. The application map must have a bean manager instance
(Found inside
org.apache.myfaces.util.ExternalSpecifications#isCDIAvailabl
e()).

When MyFaces is shared between different applications,
basing CDI availability on an application's configuration
(condition two) is an issue.

* RECOMMENDATION:                                              *
****************************************************************
JSF CDI support is set once per server. This can cause JSF
features that need CDI (for example, Faces Flows) to not work in
if a non-CDI application is loaded first.

Problem conclusion

The JSF MyFaces 2.2 code was updated so that MyFaces CDI support
is set for each JSF application.

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
