Debugging Java program by going inside JVM?

I tried to find online, but didn't find answer. Usually we debug a Java program by breaking at some line of the application.

I want to know is there a way to debug a Java program by breaking at the entry point of JVM itself?

For example, to run a simple Java program, we can do:

java Foo

My question is, how can we debug what's going into JVM (by invoking java) before our class is loaded? Is there some way to achieve this?

You may use InTrace to instrument the Classloader classes which do the loading.
