There is an override of `safeUniqueTestName()` that does a similar replacement. I think you could add there `-`. It just seemed costly and somehow overly complicated to me to re-generate a random sequence just to get rid of a character. But probably it is not costly because in most cases we only need to re-generate once. -- This is an automated message from the Apache Git Service.
