Thanks.

There are already quite a few, primarily in the serviceability area, search for “testng”.

I believe it is sufficient to include:

  28  * @modules java.base/jdk.internal.misc

or:

  28  * @modules java.base/sun.misc


We will need to update all tests depending on sun.misc.Unsafe when it moves to a separate module.
