Detecting if a CompletableFuture is cancelled from within task

I am struggling to figure out why the task is not cancelling when using CompletableFuture#cancel. Essentially, I am creating an asynchronous task, which does it's thing (time consuming), after it finishes a single "part" it checks the original future to see if it was ComplateableFuture#isCancelled.



Here's the commit (ignore some useless code) - the invocation is in the test. The archive handler checks the cancelled state.

  • Do you ever call your Compressum.cancel() method?

  • No, that was just there as a test. Will probably resort to that. Just wanted to see if could get it working with futures built-in cancelling.
