I see,
+1 for unifying the properties.
I don't quite like the naming of the fields:
String CIPHER_SUITE_LIST becomes String[] SUPPORTED_CIPHER_LIST after
split(" ").
The names are not that important as the fields are private (which is good),
however, it is really hard to follow which property goes where.
It might be JOrphanUtils.split(JMeterUtils.getPropOrDefault(...)...) would
avoid creating a String fields,
so you don't have to invent two names for basically the same thing.

It is a bit sad to have different separators for different properties.
Do you think commas could be used as separators?
