Add try-with-resources to unclosed streams

[artwo]

This PR improves the handling of input and output streams by using the try-with-resources statement to ensure that they are closed. There is a correction on how the try-with-resources is used with multiple streams which is based in this documentation.

The PR is meant to fix the remaining sonarcloud issues of #788.

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master (5.3.0), 6.0.x
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

I am not very sure what is failing in the circleci. Could you please have a look?

I don't think it's related to this change as it happens in other PRs as well. We'll take a look.

Thanks for the PR.

CircleCI failure already fixed in the master.
