I don't think the inherited AccessControlContext is widely known or even 
clearly specified. In any case, virtual threads do not want to be 
burdened with this field. For now they are specified to not support any 
permissions. The FJ common pool is another example, the threads don't 
have any permissions either (see FJP class description has more on that).
