------------------------------------
Summary: if allow_duplicate_add_to_indices, delta CAS needs to
remove all
Key: UIMA-4126
URL: https://issues.apache.org/jira/browse/UIMA-4126
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 2.7.0SDK
UIMA-4100 fixes an issue around Delta deserialization - when updating an
existing, indexed FS, by removing the FS from the index before updating the
feature values, and then adding it back.
If the JVM property uima.allow_duplicate_add_to_indices is defined, then it's
possible the FS may be added to the indices multiple times. To prevent index
corruption, in this case, loop the remove-from-index operation until it fails
to find the item in the index, so it removes all instances. And when re-adding
it back, add it back the same number of times it was removed.
