@hiddewie Thank you very much for your time and effort on this PR. The alignment to graphql-java:22.1 looks good. I manually tested it on my personal project and it is working as expected.

Before merging it, I would like to remove the unused methods in the DataLoaderDispatchingSpec.groovy test class:

• 120-123
• 177-191

@federicorispo Thanks for the review!

I removed the dead code :)

[hiddewie]

@federicorispo Is it possible to make a new (major?) version with these changes?

[federicorispo]

Yes of course, but first I would like to test the other minor dependency bumps before merge them and release a new major (in a day or two).

If you want, you can test the snapshot version 15.2.1-SNAPSHOT created on the master branch and available here
