Thank you for your answer, building the JDK myself this error goes away.
Building my own JDK was not without challenges on OSX Mavericks though:
I first mistakenly cloned the wrong repository (the JDK9 without Jigsaw. It
compiled just fine, but I of course discovered my error when javac
complained about the -modulepath switch.
Then I cloned the right repo, but it failed to compile with an “error 2”.
As I don’t know much about make, I proceeded to creating an Ubuntu VM and
after installing a load of dependencies (which the configure.sh script
tells you about very nicely!), I got it working.
I did some more “research" about the OSX build though, and i found this:
prompted me to replace the offending sections
from /hotspot/make/bsd/makefiles/gcc.make (around line 324) with the
equivalent from the non-jigsaw sources that I managed to compile
successfully. Lo and behold, this worked like a charm.
