Julian Hyde commented on CALCITE-1168:
--------------------------------------
Interesting that this case was used as an example in a paper ["A dataset for
dynamic discovery of semantic changes in version controlled software histories"
(Zhu, Li, Rubin, Chechik)|https://dl.acm.org/citation.cfm?id=3104262] as a
model JIRA case (a JIRA case, a couple of commits accompanied by test cases
that pass if and only if the commits are applied). It's flattering that they
think we do things properly!
