When does JVM Start and Stop

[ghd]

In Windows XP when does the JVM start (JRE version 1.4 and higher)?
And when does it halt?
Does the JVM start when we launch a java application (or by executing on the command prompt - java classfile)?
And does the JVM halt when the all the java applications on the system end?

According to the documentation, the JVM halts in two situations: 1. when you terminate the java application by Ctrl+C and 2. when the 'exit' method of the System class is called. But one of my friends is arguing that the JVM starts when the system is booted and doesn't halt till the system is shut down.

What happens to the GC when the JVM halts? Does it continue to run on the low priority thread, going about its good work of recycling garbage? Or does the JVM shutdown the GC too along with itself when it halts?

Does the JVM return back all the memory it had borrowed from the OS when it comes to a halt?

Is there a good source (book or website) of answers for all these questions - that would explain all the fundamentals of the interplay of a java application, the JVM, the GC, the OS, etc. ?
