      Name: stC104175 Date: 06/13/2000


      java version "1.3.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HitSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      ?@HotSpot Virtual Machine(JDK1.3.0C FCS) cause an EXCEPTION_ACCESS_VIOLATION
      error during using JVMDI.

        HotSpot Virtual Machine(JDK1.3.0C FCS) reports the following error.

      #
      # HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
      # Please report this error at
      # http://java.sun.com/cgi-bin/bugreport.cgi
      #
      # Error ID: 4F533F57494E13120E43505002D4
      #

        The above error is occured when JDK's demo applet (ArcTest) is invoked by
      following command options:

      set CLASSPATH=.;
      appletviewer -J-Xdebug -J-Xnoagent -J-Xruntrace example1.html

        Sample program is below:

        trace.dll : A dll which calls JVMDI. Which is located in PATH.
        trace.c : c source file of trace.dll
        trace.h : header file which is used by trace.c
