[jira] [Created] (AVRO-3792) GenericData compare fails for Maps size = 0 or sizes not same

Mark Paxton created AVRO-3792:
---------------------------------

             Summary: GenericData compare fails for Maps size = 0 or sizes not same
                 Key: AVRO-3792
                 URL: https://issues.apache.org/jira/browse/AVRO-3792
             Project: Apache Avro
          Issue Type: Bug
          Components: java
    Affects Versions: 1.11.2
            Reporter: Mark Paxton


Comparison of GenericData in the java avro library is incorrectly implemented.

 

Two bugs exists:

1) Shortcut returning of 'different' is wrong, since it compares m1.size() != m1.size() instead of m1.size() != m2.size()

 

2) When one of both maps are empty, the iterator throws an exception. There is no 'isEmpty' check.

 

See PR: [https://github.com/apache/avro/pull/2325]
