 * @test
 * @key stress
 *
 * @summary converted from VM testbase nsk/stress/stack/stack007.
 * VM testbase keywords: [stress, stack, nonconcurrent]
 * VM testbase readme:
 * DESCRIPTION
 *     This test provokes multiple stack overflows in the same thread
 *     by invoking synchronized 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 10000 times -- each time by trying to
 *     invoke the same recursive method for the given fixed depth
 *     of invocations (which is 100 times that depth just measured).
 *     The test is deemed passed, if VM have not crashed.
 * COMMENTS
 *     This test crashes HS versions 1.3 and 1.4 on Win32, Solaris,
 *     and Linux platforms in all execution modes. However, it passes
 *     against HS 2.0 on Win32 platform.
 *     See also the bug:
 *     4366625 (P4/S4) multiple stack overflow causes HS crash
 *
 * @requires vm.opt.DeoptimizeALot != true
 * @run main/othervm/timeout=900 Stack007
