This this good, .dot is very useful.

Minor comments PlatformClassPath:

home.resolve("lib").toFile().exists() could also be 
Files.exists(home.resolve("lib")).

"if (classes.exists() && classes.isDirectory()) { ... }" can be changed 
to "if (classes.isDirectory()) { ... }"

In Profiles.main (debugging only, not used) then you can probably drop 
the check for p1 and p2.profile==0 as they aren't needed.
