This section provides quick descriptions on JVM troubleshooting tools newly introduced in JDK 1.5.
If you look at Java tools section of the JDK 1.5 documentation page, you will see a group of new experimental tools
called "Troubleshooting Tools":
"jinfo": Prints configuration information for a given JVM process or a Java core file on the local machine
or on a remote machine through a debug server.
"jhat" - Heap Dump Browser: Starts a Web server on a Java heap dump file (eg, produced by "jmap -dump"),
allowing the heap to be browsed.
"jmap" - Memory Map: Prints shared object memory maps or heap memory details of a given JVM process
or a Java core file on the local machine or on a remote machine through a debug server.
"jsadebugd" - Serviceability Agent Debug Daemon:
Attaches to a JVM process or a Java core file and acts as a debug server for remote tools to connect.
"jstack" - Stack Trace: Prints a stack trace of threads for a given JVM process or a Java core file
on the local machine or on a remote machine through a debug server.
Note that not all functions described above are available on Windows systems.
See next sections on how to use those tools provided in JDK 1.6 on a Windows system.
