My annotator's process method begins like this:

FSIndexRepository repo = jcas.getFSIndexRepository();
I'm getting a NullPointerException at the line after that, because
repo is null. How can this happen?
Possibly relevant: the CAS I'm processing was loaded by the CVD from
an XMI file. In the CVD I see an index called
blah.blah.blah.MyType_GeneratedIndex, whereas I expected to see an
index called MyTypeIndex that we defined.
I'm a bit out of my area of expertise here, but I saw this in the
documentation for CVD:
Important: XMI CAS is a serialization format that serializes a CAS
without type system and index information. It is therefore impossible to
read in a stand-alone XMI CAS file. XMI CAS files can only be
interpreted in the context of an existing type system. Consequently, you
need to load the AE that was used to create the XMI file to be able to
load it.
Did you first load the Analysis Engine (that has the type system
specified that matches the type system of the saved XMI CAS), before
loading the XMI Cas?
