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 error indicators. Is this a recognised limitation of the common/bin/idea.sh solution?
