| * @key stress |
| * |
| * @summary converted from VM testbase nsk/stress/stack/stack005. |
| * VM testbase keywords: [stress, quick, stack, nonconcurrent] |
| * VM testbase readme: |
| * DESCRIPTION |
| * This test provokes multiple stack overflows in the same thread |
| * by invoking final recursive method for the given fixed depth of |
| * recursion (though, for a large depth). |
| * This test makes measures a number of recursive invocations |
| * before 1st StackOverflowError, and then tries to reproduce |
| * such StackOverflowError 100 times -- each time by trying to |
| * invoke the same recursive method for the given fixed depth |
| * of invocations (which is twice that depth just measured). |
| * The test is deemed passed, if VM have not crashed. |
| * COMMENTS |
| * This test crashes all HS versions (2.0, 1.3, 1.4) on all |
| * platforms (Win32, Solaris, Linux) in all execution modes |
| * (-Xint, -Xmixed, -Xcomp) in 100% of executions in which |
| * I had tryied it. |
| * See the bug: |
| * 4366625 (P4/S4) multiple stack overflow causes HS crash |
| * |
| * @requires vm.opt.DeoptimizeALot == null | vm.opt.DeoptimizeALot == false |
| * @run main/othervm/timeout=900 nsk.stress.stack.stack005 |
