Please review this trivial change which fixes a potential crasher bug
in JDK 8 Zero. JDK 10+ don't have this problem since they got fixed
with  JDK-8143245. I figured a smaller fix like this would be more
likely to get accepted as a backport. If you'd rather have JDK-8143245
backported to JDK 8, that would be fine with me too.

Testing: We've been using this patch downstream for months now without
