JStack for Java 1.5?

I want to use the JStack in a Java 1.5 VM. I found in several web pages that a version of JStack exists for this version, but I can't find it.

I have versions 1.5.0_22 and 1.5.0_10 of the JDK and jstack开发者_Python百科 is not included. It is included in Java SDK 1.6

Is it a separate download? or is it included in a different revision?

From

http://download.oracle.com/javase/1.5.0/docs/tooldocs/share/jstack.html

jstack is not currently available on Windows platforms or on the Linux Itanium platform.

Do you happen to use Windows or Itanium?
