| * @summary converted from VM testbase nsk/stress/strace/strace003. |
| * VM testbase keywords: [stress, strace] |
| * VM testbase readme: |
| * DESCRIPTION |
| * The test checks up java.lang.Thread.getStackTrace() method for many threads, |
| * that recursively invoke a native method in running mode ("alive" stack). |
| * The test fails if: |
| * - amount of stack trace elements is more than depth of recursion plus |
| * four elements corresponding to invocations of Thread.run(), Thread.wait(), |
| * Thread.exit(), Thread.yield() and ThreadGroup.remove() methods; |
| * - there is at least one element corresponding to invocation of unexpected |
| * method. |
| * This test is almost the same as nsk.stress.strace.strace001 except for |
| * the recursive method is a native one. |
| * COMMENTS |
| * Below assertion is revealed on engineer's build. It is needed to check |
| * on a promoted build. |
