-An optional unique ID to use when multiple debug servers are running on the same remote host\&.
+.B \f[I]pid\f[R]
+The process ID for which the stack trace is printed.
+The process must be a Java process.
+To get a list of Java processes running on a machine, use either the
+\f[CB]ps\f[R] command or, if the JVM processes are not running in a
+separate docker instance, the \f[B]jps\f[R] command.
+.RS
+.PP
+\f[B]Note:\f[R] JDK 10 has added support for using the Attach API when
+attaching to Java processes running in a separate docker process.
+However, the \f[CB]jps\f[R] command will not list the JVM processes that
+are running in a separate docker instance.
+If you are trying to connect a Linux host with a Virtual Machine that is
+in a docker container, you must use tools such as \f[CB]ps\f[R] to look up
+the PID of the JVM.

 .SH DESCRIPTION    
-The \f3jstack\fR command prints Java stack traces of Java threads for a specified Java process, core file, or remote debug server\&. For each Java frame, the full class name, method name, byte code index (BCI), and line number, when available, are printed\&. With the \f3-m\fR option, the \f3jstack\fR command prints both Java and native frames of all threads with the program counter (PC)\&. For each native frame, the closest native symbol to PC, when available, is printed\&. C++ mangled names are not demangled\&. To demangle C++ names, the output of this command can be piped to \f3c++filt\fR\&. When the specified process is running on a 64-bit Java Virtual Machine, you might need to specify the \f3-J-d64\fR option, for example: \f3jstack -J-d64 -m pid\fR\&.
 .PP
-\fINote:\fR This utility is unsupported and might not be available in future release of the JDK\&. In Windows Systems where the dbgeng\&.dll file is not present, Debugging Tools For Windows must be installed so these tools work\&. The \f3PATH\fR environment variable needs to contain the location of the jvm\&.dll that is used by the target process, or the location from which the crash dump file was produced\&. For example:
-.sp     
-.nf     
-\f3set PATH=<jdk>\ejre\ebin\eclient;%PATH%\fP
-.fi     
-.nf     
-\f3\fP
-.fi     
-.sp     
-.SH OPTIONS    
-.TP
--F
-.br
-Force a stack dump when \f3jstack\fR [\f3-l\fR] \f3pid\fR does not respond\&.
-.TP
--l

-Long listing\&. Prints additional information about locks such as a list of owned \f3java\&.util\&.concurrent\fR ownable synchronizers\&. See the \f3AbstractOwnableSynchronizer\fR class description at http://docs\&.oracle\&.com/javase/8/docs/api/java/util/concurrent/locks/AbstractOwnableSynchronizer\&.html

+The \f[CB]jstack\f[R] command prints Java stack traces of Java threads for
+a specified Java process.
+For each Java frame, the full class name, method name, byte code index
+(BCI), and line number, when available, are printed.
+C++ mangled names aren\[aq]t demangled.
+To demangle C++ names, the output of this command can be piped to
+\f[CB]c++filt\f[R].
+When the specified process is running on a 64\-bit JVM, you might need
+to specify the \f[CB]\-J\-d64\f[R] option, for example:
+\f[CB]jstack\ \-J\-d64\f[R] \f[I]pid\f[R].
+.PP
+\f[B]Note:\f[R]
+.PP
+This command is unsupported and might not be available in future
+releases of the JDK.
+In Windows Systems where the \f[CB]dbgeng.dll\f[R] file isn\[aq]t present,
+the Debugging Tools for Windows must be installed so that these tools
+work.
+The \f[CB]PATH\f[R] environment variable needs to contain the location of
+the \f[CB]jvm.dll\f[R] that is used by the target process, or the location
+from which the core dump file was produced.
