You don't have to delete this name, as Java is trademarked by over 34 different companies in one form or another, mostly by coffee companies as the dictionary word Java is a synonym for coffee as well as an Oracle trademark. So you could sell it to an end user without indicating what that end user should be using it for, or use it yourself as long as it's outside any Oracle trademarked classes. But if you were to use it yourself in reference to Java computer skills there is a good chance you might have a UDRP filed against you by Oracle. Good Luck to you!
