Im working on https://github.com/openjdk/jdk/pull/10920, which fixes the last of the null pointer dereferences in x86/AArch64 HotSpot. Once that's done I'm thinking of enabling `-fsanitize=null` by default in debug builds, as long as it's not too slow. ------------- PR: https://git.openjdk.org/jdk/pull/11604
