      Description

      Name: dkR10014 Date: 03/12/2002


      Build: 1.4.1-beta-b03
      Test: nsk/jdb/kill/kill001
      Platform: Solsparc, Solx86, Win, Linux
      Debuggee VM: Client, Server
      Debuggee VM mode: -Xmixed, -Xint, -Xcomp

      The test checks jdb's 'kill <thread_id> <exception_object>' command.

      The test consists of two programs:
       kill001.java - launches jdb and debuggee VM, writes command to jdb,
       kill001a.java - the debugged application.

      The debugged application creates a number of additional threads with
      the names like "MyThread-<number>" and starts them. The jdb suspends
      the debuggee at a moment after additional threads have started and
      then kills them.

      The debuggee VM crashes with core dump when it is resumed with jdb "cont"
      command after killing of additional theads.

      Below is jdb stdout log redirected to jdb.stdout file.

      How to reproduce:
       1. cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/{this_bug_number}
       2. sh doit.sh <JAVA_HOME> <JAVA_EXECUTABLE> <VM_OPTIONS>

       where <JAVA_EXECUTABLE> must be java or java_g,
        <VM_OPTIONS> are optional parameters for debuggee VM.

      The test will appear in the next testbase_nsk r13 release.
