 * @test

 * @key stress

 *

 * @summary converted from VM testbase nsk/stress/stack/stack001.

 * VM testbase keywords: [stress, quick, stack, nonconcurrent]

 * VM testbase readme:

 * DESCRIPTION

 *     Provoke StackOverflowError by infinite recursion in Java method,

 *     intercept the exception try to make one more invocation.

 * COMMENTS

 *     Kestrel for Solaris_JDK_1.3-b10 crashes while trying to execute

 *     this test with Client HS VM.

 *     See lots of bugs concerning similar failuires:

 *     Evaluated:

 *     4217960 [native stack overflow bug] reflection test causes crash

 *     Accepted:

 *     4285716 native stack overflow causes crash on Solaris

 *     4281578 Second stack overflow crashes HotSpot VM

 *     Closed (duplicate):

 *     4027933     Native stack overflows not detected or handled correctly

 *     4134353     (hpi) sysThreadCheckStack is a no-op on win32

 *     4185411     Various crashes when using recursive reflection.

 *     4167055     infinite recursion in FindClass

 *     4222359     Infinite recursion crashes jvm

 *     Closed (will not fix):

 *     4231968 StackOverflowError in a native method causes Segmentation Fault

 *     4254634     println() while catching StackOverflowError causes hotspot VM crash

 *     4302288 the second stack overflow causes Classic VM to exit on win32
