------------------------------------
Summary: uv3 deserialize compressed form 4 sofas not being indexed
correctly
Key: UIMA-5593
URL: https://issues.apache.org/jira/browse/UIMA-5593
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 3.0.0SDK-beta
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.
