Description of problem:
Referring to Pull Request on Hibernate Search project upstream: https://github.com/hibernate/hibernate-search/pull/759
We're introducing a reflective call to allow using a feature which was introduced in JDG only but not available in a community build, making it very complex to add an integration test in Hibernate Search itself.
To make sure this works and prevent future regressions we should introduce an integration test for this feature in the JDG codebase.
Goal: improve indexing performance
