   <!--
   
   *Thank you very much for contributing to Apache Avro - we are happy that you 
want to help us improve Avro. To help the community review your contribution in 
the best possible way, please go through the checklist below, which will get 
the contribution into a shape in which it can be best reviewed.*
   
   *Please understand that we do not do this to make contributions to Avro a 
hassle. In order to uphold a high standard of quality for code contributions, 
while at the same time managing a large number of contributions, we need 
contributors to prepare the contributions well, and give reviewers enough 
contextual information for the review. Please also understand that 
contributions that do not follow this guide will take longer to review and thus 
typically be picked up with lower priority by the community.*
   
   ## Contribution Checklist
   
     - Make sure that the pull request corresponds to a [JIRA 
issue](https://issues.apache.org/jira/projects/AVRO/issues). Exceptions are 
made for typos in JavaDoc or documentation files, which need no JIRA issue.
     
     - Name the pull request in the form "AVRO-XXXX: [component] Title of the 
pull request", where *AVRO-XXXX* should be replaced by the actual issue number. 
       The *component* is optional, but can help identify the correct reviewers 
faster: either the language ("java", "python") or subsystem such as "build" or 
"doc" are good candidates.  
   
     - Fill out the template below to describe the changes contributed by the 
pull request. That will give reviewers the context they need to do the review.
     
     - Make sure that the change passes the automated tests. You can [build the 
entire project](https://github.com/apache/avro/blob/master/BUILD.md) or just 
the [language-specific 
SDK](https://avro.apache.org/project/how-to-contribute/#unit-tests).
   
     - Each pull request should address only one issue, not mix up code from 
multiple issues.
     
     - Each commit in the pull request has a meaningful commit message 
(including the JIRA id)
   
     - Every commit message references Jira issues in their subject lines. In 
addition, commits follow the guidelines from [How to write a good git commit 
message](https://chris.beams.io/posts/git-commit/)
       1. Subject is separated from body by a blank line
       1. Subject is limited to 50 characters (not including Jira issue 
reference)
       1. Subject does not end with a period
       1. Subject uses the imperative mood ("add", not "adding")
       1. Body wraps at 72 characters
       1. Body explains "what" and "why", not "how"
