Adam Lally commented on UIMA-547:
---------------------------------

Also looks like it could affect XCAS deserialization for certain array types (boolean,short,long,double).

> If the JCAS has been initialized, subsequently attempting to deserialize an XMI CAS containing an array will fail with an error message such as:
> java.lang.ClassCastException: org.apache.uima.jcas.cas.StringArray cannot be cast to org.apache.uima.cas.impl.FeatureStructureImplC
> The XmiCasDeserializer is incorrectly trying to typecast to FeatureStructureImplC, which is the implementation class used only in non-JCAS scenarios.  It is surprising we did not see this before.
