idea (non-blocker): we could have a utility type for making properties. It might make this a little easier for humans to parse.

Maybe we already have something available, but this helps close the comment on the linked PR so it can be merged.

I'm thinking something like:

pub struct Properties(BTreeMap);
impl Display for JreProperties {
 fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
 todo!("iterate over the properties in self.0 and make -Dproperty=value joined by space");
 // write!(f, "{}", self.0)
 }
}
impl DerefMut for Properties {
 ...
}
