  28  * @summary converted from VM testbase nsk/stress/stack/stack004.
  29  * VM testbase keywords: [stress, stack, nonconcurrent]
  30  * VM testbase readme:
  31  * DESCRIPTION
  32  *     This test provokes multiple stack overflows in the same thread
  33  *     by invoking final static recursive method for the given fixed
  34  *     depth of recursion (though, for a large depth).
  35  *     This test makes measures a number of recursive invocations
  36  *     before 1st StackOverflowError, and then tries to reproduce
  37  *     such StackOverflowError 100 times -- each time by trying to
  38  *     invoke the same recursive method for the given fixed depth
  39  *     of invocations (which is twice that depth just measured).
  40  *     The test is deemed passed, if VM have not crashed.
  41  * COMMENTS
  42  *     This test crashes all HS versions (2.0, 1.3, 1.4) on all
  43  *     platforms (Win32, Solaris, Linux) in all execution modes
  44  *     (-Xint, -Xmixed, -Xcomp) in 100% of executions in which
  45  *     I had tryied it.
  46  *     See the bug:
  47  *     4366625 (P4/S4) multiple stack overflow causes HS crash
  48  *
  49  * @requires vm.opt.DeoptimizeALot == null | vm.opt.DeoptimizeALot == false
