The simplest explanation for what you're seeing would
be that the type system is somehow not loaded.  The
annotator requests a type object from the the type
system, and doesn't check that it's not null.  The
type object is then handed to createFS(), which
barfs on a null type.  To verify, put a break point
on line 165 of MarkupHandler.  attributeType must
not be null.  If it's null, that probably means the
type system is not loaded.  Did you change the
descriptors?  Any error messages on startup, in the
UIMA log?

(That code is using a mixture of JCas and
plain old CAS, which I don't quite understand.  That
should have no bearing on your issue, however.)
