All FFM benchmark that depend on Unsafe fail with:

java.lang.IllegalAccessError: class org.openjdk.bench.java.lang.foreign.Utils (in unnamed module @0x7ab2bfe1) cannot access class jdk.internal.misc.Unsafe (in module java.base) because module java.base does not export jdk.internal.misc to unnamed module @0x7ab2bfe1

This has been caused by JDK-8332744. That fix replaced sun.misc.Unsafe with jdk.internal.Unsafe, but forgot to export the internal Unsafe package to ALL-UNNAMED.
