 * @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

 *

 * @run main/othervm nsk.stress.stack.stack006
