Q: Multithreaded logger

What is the test to do? Fail if there is a FIXME? How many FIXMEs do you currently have? None? More than that? Would you rather have a failing test or the FIXMEs? Would you want to fail the build if there are FIXMEs? Note also that tests printing stuff is IMHO an anti-pattern... tests pass or fail. You shouldn't need to manually inspect the output. Not sure what you want exactly, but honestly I'd settle for the tasks view in Eclipse, your CI server, code reviews, or SonarQube. — Robert just now

@FranciscoNúñez okay... I thought I saw that once when an answer was updated but perhaps just when the OP left a comment
 
@SᴀᴍOnᴇᴌᴀ I usually receive notifications of comments or new answers, every time you add something leave me a comment to find out ... I also recommend that you migrate anything new that you add to the new question. since there is new and updated code up to version 1.0.6; as I am quite enthusiastic about this little project, it is very likely that version 1.1.0 will be here this week.
