      {}Following test project has been created to reproduce the error: https://github.com/fmiguelez/test-undertow-2620

      The test suite includes two tests:

      •   A test with a small payload (less than 16KB) that succeeds.
      •   A test with a large payload (greater than 16KB) that fails, demonstrating the bug.

      If parent is changed to spring-boot-starter-parent:3.5.5 (instead of 3.5.6) tests pass.
