Comparison method violates its general contract!

Hello all,

I am running a kettle transformation on Kettle 4.4.0. The issue I am having with this is the i get the following error when running the transformation

Exception in thread "Thread-32" java.lang.IllegalArgumentException: Comparison m
ethod violates its general contract!

This issue only happens when I run the transformation. When I run the job that holds this transformation, the transformation runs fine.
Does anyone have any experience with this error and what causes it. Some extra information the job is on a server, but I can run it locally with no issues,
just on the server I get this error.

Thank you
