It will be printed in case the  checkHsErrFileContent  fails,  So we do not have to set 'verbose' and print the content always (because in the successful case it is not really needed) but only in failure case.

I want to print it to see what was wrong with the hserr file content.  Especially in the SecondaryErrorTest we had errors where we missed the hserr content to look WHAT exactly was really bad/failing.
