After running java -prof MyClass.java the .prof file does not contain timing data for any methods in MyClass. It only contains timing info for classes in the java and sun packages.

I've created the following example to illustrate...
I compiled this...
public class MyClass {
public static void main(String args[])
{
MyClass obj= new MyClass();
obj.method1();
obj.method2();
obj.method2();
}
void method1() {
method2();
method3();
}
void method2() {
method3();
}
void method3() {
}
}

and when I run java with the -prof option I get this output (sorry, I know its hard to read but notice that there's not even a
mention of "MyClass", what gives????)....
