    Description

      It seems that JDK-8304303 introduced a memory leak. When running some jvmti tests the VM allocates a lot of memory without freeing it.
      I could track it down with NMT (using -XX:MallocLimit=internal:3g -XX:NativeMemoryTracking=detail) to be allocated in SharedRuntime::notify_jvmti_unmount/mount.
