The TCK test failure message reports
> failures.forEach(f -> System.out.printf("%s%n", f));
where f is the failure reason. There is also a verbose option which prints out the stack trace where the failure was reported. But in some failure cases these two pieces of information are insufficient to debug the failure. It would be nice if the resources that participated in the test also logged information which could be reported for more effective analysis of the reasons for the failure. This last requirement may affect the TCK itself so the code in the eclipse microprofile-lra repo should be analysed as well.
