HotSpot 1.3fcs-K (solaris) crashes when StackOverflowError occurs in
a loop.
Win32 VM in mixed mode outputs this message once and silently exits
which does not look correct as well.
Classic and win32 VM in -Xint mode output expected triple
"StackOverflowError exception occurred" message.
Log and test source follow:

HotSpot crashes when second stack overflow occurs. Classic does not.

JCK testsuite cannot be passed in singleJVM mode because
of this bug: there are two tests in JCK that throw StackOverflowError
(vm/concepts/exceptions/exceptions031/exceptions03101 and
vm/concepts/exceptions/exceptions031/exceptions03102)

Test program
--------------------------------------------- test.java ---

public class test {
   public static void main(String[] args) {
      overflow("First overflow");
      overflow("Second overflow");
   }
   static void runner() {
      runner();
   }
   static void overflow(String msg) {
      try {
         runner();
      } catch (StackOverflowError e) {
         System.out.println(msg);
      }
   }
}

Being run on WinNT, HotSpot crashes too, without
any diagnostics but with exitcode 128.
