[MWRAPPER-123] only-mvnw fails on ksh printf implementations #245

Benjamin Marwell opened MWRAPPER-123 and commented

the script only-mvnw contains this snippet in a line to calculate a hash:

printf %d "'$str"

The idea is to convert $str to a number, where ' has a special meaning for %d conversion. However, there is a major problem with it:

It does not work on any ksh (and maybe other shells, too), because the behaviour of this conversion is undefined: https://pubs.opengroup.org/onlinepubs/9699919799/functions/printf.html

Instead, just do a conversion char-by-char.

Affects: 3.1.1
