I do this manually quite often, due to "write-once-debug-everywhere" 
nature of the JVM for Isabelle/Scala and Isabelle/jEdit.

This did not work out so far, although to do it professionally we would 
have to do regular isatest runs for Windows/Cygwin, too.

the latest problems.

Since Isabelle2013, I've never updated the underlying Cygwin.

You can also install that independently, using setup options seen here:
