No, I don't think msys currently works out out of the box. There's a 
silly show-stopper in the configure script, 
https://bugs.openjdk.java.net/browse/JDK-8022177.

But actually, I'm just proposing that it should fail with style on msys. 
:-) Something like this would be acceptable to me, given that msys is 
currently not working anyhow.

if test "x$OPENJDK_BUILD_OS_ENV" = "xwindows.cygwin"; then
   BOOT_RTJAR=`cygpath -u -p "$BOOT_RTJAR" | $TR ':' ';'`
elif test "x$OPENJDK_BUILD_OS_ENV" = "xwindows.msys"; then
   AC_MSG_ERROR([BOOT_RTJAR handling is unfortunately not supported on 
msys yet])
endif

So we at least get a proper error message on msys. Otherwise we will get 
a weird BOOT_RTJAR path errors down the line which will be hard to track.
