Review comment:
Probably better to define the Pattern once as a class-level static final
field *or* use the String class' `replace` such as `prop.replace("\\s+$", "")`,
although I'd guess using the pre-compiled Pattern would be slightly more
efficient... but this code is probably only run once at startup anyway so it's
unlikely a big deal (but I'd still prefer Pattern not to be compiled every time
within the `while` loop)
