Yes, it is accessible. From the looks of it, GC SEGVed on NULL object. Which might indicate heap
corruption. Unfortunately, hs_err does not indicate much to get more close bearing on the problem.

I have a few suggestions to try:

 *) Run with -XX:+ShenandoahVerify: this will catch if the bug is indeed the heap corruption;

 *) Run with the latest release build, either self-built, or from here:
   https://builds.shipilev.net/openjdk-shenandoah-jdk8-release/

   I think it would be enough to IDEA_JDK=... idea-install-folder/bin/idea.sh

 *) Run with the latest fastdebug build:
   https://builds.shipilev.net/openjdk-shenandoah-jdk8-fastdebug/

 *) Wait for upcoming 8u151, that will come with other fixes

I am running CLion with shenandoah/jdk8 myself for months, and have seen no problems so far.

Thanks,
