Ok. There are Unsafe tests in:

  hotspot/test/runtime/Unsafe

So we could place it there.

In this particular case i think we would need to run without and with the flag UseUnalignedAccesses set to false. IIUC that just means two @run entries defined for jtreg to crunch on e.g.:

/* 
 * @test 
 * @bug XXXXXXX 
 * @run TestUnalignedAccess
 * @run main/othervm -XX:-UseUnalignedAccesses TestUnalignedAccess
 */
