Query on developing OpenJDK with IntelliJ

Hi Staffan and Maurizio,
Thanks for the pointers! The script which the email thread refers to
(jdk9/common/bin/idea.sh) helped me get rid of those useless red squiggles.
However, I now have a new problem, where not just the useless red squiggles
but also the useful ones are gone as well; they don't even show up when I
write syntactically invalid code like "System.out.pr".
Additionally, whereas before my editor performed code analysis and
highlighting on-the-fly e.g. pointing out unused imports, it now doesn't
seem to do so anymore.
I've read http://stackoverflow.com/a/30810965/2252930 and tried
closing/reopening IntelliJ and invalidating the caches, but they both don't
seem to solve my problem.
I've found I can run Analyze -> Inspect Code... to do manual code
analysis, but it doesn't solve my problem of completely lacking any useful
Is this a recognised limitation of the common/bin/idea.sh solution?
