31
 * DESCRIPTION
32
 *     This test provokes multiple stack overflows in the same thread
33
 *     by invoking final static recursive method for the given fixed
34
 *     depth of recursion (though, for a large depth).
35
 *     This test makes measures a number of recursive invocations
36
 *     before 1st StackOverflowError, and then tries to reproduce
37
 *     such StackOverflowError 100 times -- each time by trying to
38
 *     invoke the same recursive method for the given fixed depth
39
 *     of invocations (which is 200 times that depth just measured).
40
 *     The test is deemed passed, if VM have not crashed.
41
 * COMMENTS
42
 *     This test crashes all HS versions (2.0, 1.3, 1.4) on all
43
 *     platforms (Win32, Solaris, Linux) in all execution modes
44
 *     (-Xint, -Xmixed, -Xcomp) in 100% of executions in which
45
 *     I had tryied it.
46
 *     See the bug:
47
 *     4366625 (P4/S4) multiple stack overflow causes HS crash
