 * @test
 * @key stress
 *
 * @summary converted from VM testbase nsk/stress/stack/stack006.
 * VM testbase keywords: [stress, stack, nonconcurrent]
 * VM testbase readme:
 * DESCRIPTION
 *     This test provokes multiple stack overflows in the same thread
 *     by invoking virtual recursive method for the given fixed depth
 *     of recursion (though, for a large depth).
 *     This test makes measures a number of recursive invocations
 *     before 1st StackOverflowError, and then tries to reproduce
 *     such StackOverflowError 100 times -- each time by trying to
 *     invoke the same recursive method for the given fixed depth
 *     of invocations (which is twice that depth just measured).
 *     The test is deemed passed, if VM have not crashed.
 * COMMENTS
 *     This test crashes all HS versions (2.0, 1.3, 1.4) on all
 *     platforms (Win32, Solaris, Linux) in all execution modes
 *     (-Xint, -Xmixed, -Xcomp) in 100% of executions in which
 *     I had tryied it.
 *     See the bug:
 *     4366625 (P4/S4) multiple stack overflow causes HS crash
 *
 * @requires vm.opt.DeoptimizeALot != true
 * @run main/othervm/timeout=900 nsk.stress.stack.stack006
