Given the stacktrace, from a previous email in this thread,
does it make more sense to wrap the IPE in an IOException,
rather then declaring that the ZipFile constructor can throw
IPE?  The reason I suggest this is that it looks, from that
stacktrace, that the error is detected deep in the
implementation, rather than when performing argument
validation.

If this is not the case, then maybe the implementation could
be updated to perform the toPath operation earlier, or at
least add some comment indicating the implicit arg check.
