 * @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
