NAME
jstack - stack trace
SYNOPSIS
jstack [ option ] pid
jstack [ option ] executable core
jstack [ option ] [server-id@]remote-hostname-or-IP
DESCRIPTION
jstack 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.
NOTE - This utility is unsupported and may or may not be available in
future versions of the J2SE SDK. jstack is not currently available on
Windows platforms or on the Linux Itanium platform.
PARAMETERS
Options are mutually exclusive. Option, if used, should follow immedi-
ately after the command name.
pid 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.
executable Java executable from which the core dump was produced.
core core file for which the stack trace is to be printed.
remote-hostname-or-IP
remote debug server's (see jsadebugd) hostname or IP
address.
server-id optional unique id, if multiple debug servers are run-
ning on the same remote host.
OPTIONS
-m prints mixed mode (both Java and native C/C++ frames)
stack trace.
-h Prints a help message.
-help Prints a help message.

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