Journal: What is this Journal thing?

I'd seeing something wierd with JDK 1.4.2:

$ javap java.lang.Object
Compiled from "Object.java"
public class java.lang.Object{
        public native int hashCode();
        static {};
        public java.lang.Object();
        protected void finalize();
              throws java/lang/Throwable
        public final native void notify();
        public final native void notifyAll();
        public final void wait();
              throws java/lang/InterruptedException
        public final native void wait(long);
              throws java/lang/InterruptedException
        public final void wait(long,int);
              throws java/lang/InterruptedException
        public final native java.lang.Class getClass();
        protected native java.lang.Object clone();
              throws java/lang/CloneNotSupportedException
        public boolean equals(java.lang.Object);
        public java.lang.String toString();
}
