------------------------------------
Summary: uv3 throw new exception v2 binary delta deserialization
Key: UIMA-5185
URL: https://issues.apache.org/jira/browse/UIMA-5185
Project: UIMA
Issue Type: Improvement
Components: Core Java Framework
Reporter: Marshall Schor
Assignee: Marshall Schor
Priority: Minor
Fix For: 3.0.0SDKexp
Version 3 models the v2 layout by scanning all reachable FSs; this drops
(versus v2) unreachable FSs. Binary form deltas encode the changes relative to
this model. Because the model for v3 doesn't match v2's (due to the omission of
unreachable FSs), delta updates can't be handled when reading a v2-generated
delta cas into a v3 instance.
Throw an exception for this case (using binary deserializing of Delta CASs
generated using V2 into a V3 instance). Document this in the backwards
compatibility section.
