  * @summary Test that when saving a class initialization failure caused by
  *          a StackOverflowError, that we record the SOE as the underlying
  *          cause, even if we can't create the ExceptionInInitializerError
- * @requires os.simpleArch == "x64"
- * @comment The reproducer only fails in the desired way on x64.
- * @requires vm.flagless
  * @comment This test could easily be perturbed so don't allow flag settings.
- *
- * @run main/othervm -Xss160K -Xint TestStackOverflowDuringInit
+ * @requires vm.flagless
+ * @comment Run with the smallest stack possible to limit the execution time.
+ *          This is the smallest stack that is supported by all platforms.
