Bug in Files.copy() where the source Path is a directory... It _is_ a bug, right?

I don't know if anyone is maintaining a catalog anywhere, we usually 
only hear about custom providers when folks show up here with questions 
or bug reports.

A quick search finds a number of providers, one for Amazon S3 (that I 
wasn't aware of), ssh, CIFS, and one for ZIP and several other archive 
formats. I don't know how complete they are of course.

In the JDK then we've included the zip provider since JDK 7 and a new 
one in JDK 9 is the "jrt" file system that is a read-only file system to 
access the class and resources files in a runtime image (this is what 
javac and other tools in the JDK now use).

In general then creating file system providers has been somewhat of a 
niche (but fun) area. It would be good to do a survey of what exists, 
create a catalog and see if there are opportunities to collaborate.
