jstack - Unix, Linux Command
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.

Options are mutually exclusive. Option, if
