URL guarantees that the ftp protocol handler is present, worth re-considering this?

[Alan Bateman]

java.net.URL guarantees that 5 protocol handlers are present: http, 
https, ftp, file and jar.

ftp a legacy protocol and I'm wondering whether it's time to consider 
removing it from the list. I'm not suggesting we don't continue to 
include it, rather just removing the guarantee that it is always 
present. The motivation for bringing this up is modules and compact 
profiles where it might be desirable to not include the ftp protocol 
handler for footprint reasons.
