Thanks for the pointer Max, but I think I managed to figure out what my new problem was and to find a solution for it.
In my current dev setup, I'm running IntelliJ on Windows connected to a Samba network share which holds my jdk9 clone, which itself is hosted on an Ubuntu VM on my local machine (as per https://adoptopenjdk.gitbooks.io/adoptopenjdk-getting-started-kit/content/en/virtual-machines/sharing_host_folder_with_guest_vm.html ). Convoluted, yeah, I know. Since IntelliJ was running off a network share, it would frequently synchronize with the jdk9 files but do so very, very slowly. Since I initially ran just jdk9/common/bin.idea.sh to generate my IntelliJ project, it created a project for the entire source code of jdk9, and this combined with the slow file synchronization caused the IntelliJ editor's usual analysis to freeze. To resolve this, I disabled automatic file synchronization, deleted my IntelliJ project files and regenerated them using "jdk9/common/bin/idea.sh java.base" (since java.base was the only module I was interested in), and increased my IntelliJ heap size to "-Xmx1024m". Afterwards, things quickly went back to normal for me. I hope this info proves useful for other IntelliJ users on the OpenJDK mailing lists.
