> Traced a strange bug to the deserialization for form 4 compressed - getting a
> NPE. Root cause is the index info being deserialized is written with a
> conversion that changes the "address" of FSs to incrementing indexes (because
> they compress better). But the serialization code doesn't do this for Sofas.
> Mostly this doesn't matter by accident. But the special test case done in
> DocumentAnnotation test trips this bug.
> Fix is in deserialization: after reading the sofa index number (which was
> written as v2 addresses, not converted to sequential) is to convert it to
> sequential so the rest of the code (which expects this) works. In v2, not an
> issue, but an improvement was made in v3 which broke this.
