Marshall Schor commented on UIMA-3054:
--------------------------------------
This is an actual bug. It was missed in the test cases because they didn't
have a case where the sofa occurred after some other feature structure.
The bug: (for the curious, only:) In form 6, there's a translation from
absolute FS addresses to a sequence number, which is serialized. This is done
for multiple reasons; there needs to be a corresponding reverse-translation
when deserializing. This was missing but just for the case of a sofa FS which
are handled specially.

> Binary CAS format 6 leaves document text "null" after deserializing.
> On my machine (uimaj 2.4.1-SNAPSHOT) this fails in the last line, claiming
