Key: UIMA-5346
URL: https://issues.apache.org/jira/browse/UIMA-5346
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 3.0.0SDK-alpha02
BinaryCasSerDes6 has a method used for sort comparison. At one point in
testing, a test case threw an IllegalArgumentException from TimSort, one of the
implementations of sort in Java, where it determined some invalid state due to
the sortCompare not obeying the contract.
This could be due to equals(fs1, fs2) == false and sortCompare(fs1, fs2) == 0.
Fix this in two places: Add equals method for FeatureStructureImplC that
returns 0 if the _id fields are the same. This matches the hashcode for that.
Change the sortCompare function to only return 0 if the id's are the same.
