31 * DESCRIPTION
32 * This test provokes multiple stack overflows in the multiple
33 * threads -- by invoking static recursive method for the given
34 * fixed depth of recursion (though, for a large depth).
35 * This test measures a number of recursive invocations until
36 * stack overflow, and then tries to provoke similar stack overflows
37 * 10 times in each of 10 threads. Each provocation consists of
38 * invoking that recursive method for the given fixed depth
39 * of invocations which is 10 times that depth measured before.
40 * The test is deemed passed, if VM have not crashed, and
41 * if exception other than due to stack overflow was not
42 * thrown.
43 * COMMENTS
44 * This test crashes HS versions 2.0, 1.3, 1.4 on Win32 and Solaris
45 * platforms.
46 * See the bug:
47 * 4366625 (P4/S4) multiple stack overflow causes HS crash
