Two related problems are fixed by this APAR:
1. A java.util.EmptyStackException is thrown when accessing an
injected field of type javax.enterprise.inject.Instance that
is created by a producer method that uses
javax.enterprise.inject.spi.InjectionPoint as a parameter.
2. A java.lang.ClassCastException is thrown when resolving an
injected field of type javax.inject.Provider.

Problem conclusion

The CDI implementation was modified to correctly inject and
access instances of Instance and Provider. To enable the fix
for this APAR, the following JVM custom property must be set
to "true": (default=false)
com.ibm.ws.webbeans.trackInjectionPointsWithStack

For details on how to set a JVM property, refer to the article
"Java virtual machine custom properties" in the Information
Center for your WebSphere Application Server version and
operating system.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.9 and 8.5.5.3.  Please refer to the
