------------------------------------

             Summary: Avro should not use new HashMap(targetSize) in generated code for records
                 Key: AVRO-2731
                 URL: https://issues.apache.org/jira/browse/AVRO-2731
             Project: Apache Avro
          Issue Type: Improvement
            Reporter: Roman Leventov


[https://github.com/apache/avro/blob/4a1e3acdc09de0545cbb6bfd4554604e64ca1a35/lang/java/compiler/src/main/velocity/org/apache/avro/compiler/specific/templates/java/classic/record.vm#L808]

This is improper usage of HashMap constructor. See Guava's [Maps.newHashMapWithExpectedSize|[https://github.com/google/guava/blob/6e0c5b5d50a3e457ae0d787f7c9be7b48c10120b/guava/src/com/google/common/collect/Maps.java#L306-L337]] code for details.
