NAME
       jstack - stack trace

SYNOPSIS
       jjssttaacckk [ option ] pid
       jjssttaacckk [ option ] executable core
       jjssttaacckk [ option ] [server-id@]remote-hostname-or-IP

DESCRIPTION
       jjssttaacckk  prints  Java  stack  traces  of  Java  threads for a given Java
       process or core file or a remote debug server. For each Java frame, the
       full  class name, method name, 'bci' (byte code index) and line number,
       if available, are printed. With the -m option, jstack prints both  Java
       and native frames of all threads along with the 'pc' (program counter).
       For each native frame, the closest native symbol to 'pc', if available,
       is printed. C++ mangled names are not demangled. To demangle C++ names,
       the output of this command may be piped to c++filt.

       NNOOTTEE - This utility is unsupported and may or may not be  available  in
       future  versions of the J2SE SDK.  jjssttaacckk iiss nnoott currently available on
       Windows platforms or on the Linux Itanium platform.

       ppiidd            process  id  for  which the stacktrace is to be printed.
                      The process must be a Java process. To  get  a  list  of
                      Java processes running on a machine, jps may be used.

       -mm             prints  mixed  mode  (both Java and native C/C++ frames)
                      stack trace.

       Mixed mode stack trace, the -mm option, does not work  with  the  remote
       debug server.
