28 * @summary converted from VM testbase nsk/stress/stack/stack002.
29 * VM testbase keywords: [stress, quick, stack, nonconcurrent]
30 * VM testbase readme:
31 * DESCRIPTION
32 * Provoke StackOverflowError by infinite recursion in Java method,
33 * intercept the exception and continue to invoke that method until
34 * the test exceeds timeout, or until Java VM crashes.
35 * COMMENTS
36 * I believe that the test causes HS crashes due to the following bug:
37 * 4330318 (P2/S2) NSK test fails as An irrecoverable stack overflow
38 * See also bugs (lots of bugs!):
39 * Evaluated:
40 * 4217960 [native stack overflow bug] reflection test causes crash
41 * Accepted:
42 * 4285716 native stack overflow causes crash on Solaris
43 * 4281578 Second stack overflow crashes HotSpot VM
44 * Closed (duplicate):
45 * 4027933 Native stack overflows not detected or handled correctly
46 * 4134353 (hpi) sysThreadCheckStack is a no-op on win32
47 * 4185411 Various crashes when using recursive reflection.
48 * 4167055 infinite recursion in FindClass
49 * 4222359 Infinite recursion crashes jvm
50 * Closed (will not fix):
51 * 4231968 StackOverflowError in a native method causes Segmentation Fault
52 * 4254634 println() while catching StackOverflowError causes hotspot VM crash
53 * 4302288 the second stack overflow causes Classic VM to exit on win32
54 *
55 * @run main/othervm nsk.stress.stack.stack002
