------------------------------------------------
Summary: Spurious multipleReferencesAllowed warning when
serializing empty arrays
Key: UIMA-6377
URL: https://issues.apache.org/jira/browse/UIMA-6377
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 3.2.0SDK
Reporter: Richard Eckart de Castilho
Assignee: Richard Eckart de Castilho
Fix For: 3.2.1SDK
Empty arrays (FSArray) in UIMA are basically immutable. It is not possible to
resize an array and also there are no elements within the empty array which can
be replaced.
The deserialization code for some formats makes use of this fact and if it
encounters an empty array, it just creates one empty array instance and then
references that from all feature structures which need an empty array as their
value.
When serializing such a CAS later, however, we get warnings if
{{multipleReferencesAllow=true}} is not set on these features referencing the
shared empty array.
The serialization code producing that warning needs to be changed to not issue
a warning if the array in question is empty - because sharing then is
absolutely ok since the array is immutable and empty.
