Review comment:
the exception args no longer reflect the equality operands. could this
message become confusing (e.g. if the two do match on their own, but however
didn't upon mapping through `this.targetFs.resolvePath()`)?

Review comment:
I was actually contemplating similar (boolean flag) above, when I saw
two code paths to the same exception thrown. since java has no widespread,
canonical lib for converting exception control flow into values (like scala's
https://www.scala-lang.org/api/2.12.4/scala/util/control/Exception$.html )
there's no simple way to phrase this.
as this already recurs twice, I'd seek a utility abstraction. maybe just a
static method taking a `FileSystem` and two 'locations' (what we call
`.getDataLocation()` on). it would be an equality predicate (capturing any
exception within and converting to `false`).
