      JDK-8214976 introduced a way to forbid functions from being called outside of explicitly allowed contexts. Kim Barrett proposed [1] to use that functionality to forbid raw malloc and friends. That would have prevented JDK-8289477, where on Alpine the muslc sneaked in raw malloc and free calls via C-runtime defined standard macros.
