Just to close off this thread, I got around the issue by using the entire JDK, it would appear that just using jmap on its own doesn't work with the standard JVM libraries (no doubt jmap needs specific libraries that only come with the JDK). I just put the JDK (downloaded and extracted straight from the downloads website) in it's own directory on the server, and called jmap directly from there, which worked a treat.
