I would propose to have this workaround for now, and decide on it later for macos/x86 and macos/aarch64 at once. Sorry for chiming in so late.

Hello Anton.
Please keep JDK-8020753 away from this port, as JDK-8020753 was very intel-specific workaround and macos11.0 on aarch64 doesn't show any signs of original bug.
