 * @test
 * @key stress
 *
 * @summary converted from VM testbase nsk/stress/stack/stack009.
 * VM testbase keywords: [stress, quick, stack, nonconcurrent]
 * VM testbase readme:
 * DESCRIPTION
 *     The test provokes second stack overflow from within the
 *     stack overflow handler.
 *     This test measures a number of recursive invocations until
 *     StackOverflowError, and then tries to make an invocation
 *     for the fixed invocations depth from within the "catch"
 *     block just caught the 1st stack overflow. The depth of new
 *     invocations is 10 times that depth seen at the 1st stack
 *     overflow; so that another stack overflow occurs.
 *     The test is deemed passed, if VM have not crashed, and
 *     if there is no exception thrown other than due to stack
 *     overflow.
 * COMMENTS
 *     This test crashes HS versions 2.0, 1.3, and 1.4 on Win32
 *     and Solaris platforms.
 *     See the bug:
 *     4366625 (P4/S4) multiple stack overflow causes HS crash
 *
 * @requires vm.opt.DeoptimizeALot == null | vm.opt.DeoptimizeALot == false
 * @run main/othervm nsk.stress.stack.stack009
