I have a feature that includes a linux, win32, nl1, and nl2 child features 
(listed in that order). When installing the feature on a win32 platform, an 
ArrayStoreException (see trace below) is thrown which causes the feature to be 
disabled.

This is caused by the following:
The TargetFeature's included feature refs list contains the following: 
UpdateSiteIncludedFeatureReference (linux feature), IncludedFeatureReference 
(win32 feature), UpdateSiteIncludedFeatureReference (nl1 feature), 
UpdateSiteIncludedFeatureReference (nl2 feature) (in that order). When 
Feature.getRawIncludedFeatureReferences is called, it tries to create an array 
of type UpdateSiteIncludedFeatureReference (first listed feature reference) 
and fails because the second listed feature reference is an 
IncludedFeatureReference.

Note that if the win32 child feature was listed first and you installed on 
win32, then the array would be an IncludedFeatureReference array and we would 
not have any problems.

I'll attach a screen shot of my debug env.
