These are certainly welcome.

I took a fresh look at what is possible, and got much closer to my ultimate
goal of letting JavacFileManager do all the dirty work of dealing with
ct.sym and MR JARs (not to mention --patch-module / --module-path etc)

https://gist.github.com/2d1f8ab484427d032dc99bbbced92861

The missing link is JDKPlatformProvider, which is not exposed in
javax.tools. Would be be possible to expose this? JDKs that don't want to
support platform versioning would be only need to accept the running JDK
version. I'll be able to workaround this in the meantime at the cost of
coding against the ct.sym format.
