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.

Without trying, I would guess it is just a normal incident of the "rolling 
release" scheme of Cygwin.  Thus you always get "latest" things, including 
the latest problems.

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

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