Hello Mikhail, since we are updating these tests to move away from the shell tests, could you also see if the `deadlock.jar` file which has been committed into the repo, can be generated dynamically within the test itself. There are several ways we could do that and some other tests already have examples, but I think the main thing to look into is what exactly that (signed) jar contains to see if it is feasible to generate it dynamically.
