* @summary converted from VM testbase nsk/stress/stack/stack002.

|
|
* DESCRIPTION
|
|
* Provoke StackOverflowError by infinite recursion in Java method,
|
|
* intercept the exception and continue to invoke that method until
|
|
* the test exceeds timeout, or until Java VM crashes.
|
|
* COMMENTS
|
|
* I believe that the test causes HS crashes due to the following bug:
|
|
* 4330318 (P2/S2) NSK test fails as An irrecoverable stack overflow
|
|
* See also bugs (lots of bugs!):
|
|
* Evaluated:
|
|
* 4217960 [native stack overflow bug] reflection test causes crash
|
|
* Accepted:
|
|
* 4285716 native stack overflow causes crash on Solaris
|
|
* 4281578 Second stack overflow crashes HotSpot VM
|
|
* Closed (duplicate):
|
|
* 4027933 Native stack overflows not detected or handled correctly
|
|
* 4134353 (hpi) sysThreadCheckStack is a no-op on win32
|
|
* 4185411 Various crashes when using recursive reflection.
|
|
* 4167055 infinite recursion in FindClass
|
|
* 4222359 Infinite recursion crashes jvm
|
|
* Closed (will not fix):
|
|
* 4231968 StackOverflowError in a native method causes Segmentation Fault
|
|
* 4254634 println() while catching StackOverflowError causes hotspot VM crash
|
|
* 4302288 the second stack overflow causes Classic VM to exit on win32
|
|
*
|
|
* @requires vm.opt.DeoptimizeALot != true
|
|
* @run main/othervm/timeout=900 nsk.stress.stack.stack002
