I downloaded that and it uses the same native methods.

This file did not exist. There was a file called jdk-1.1.6.tgz but
it also used the undefined (in japhar) native methods.

I still do not get it. The problem is not with the name of the init
method (japhar works if it is called initializeSystemClass or <init>)
but it crashes when calling the native methods that japhar does not
define.
(signature of the Methods in java.lang.System)
private static native void setIn0(InputStream in);
private static native void setOut0(PrintStream out);
private static native void setErr0(PrintStream err);
What about these methods? If they are not defined then how is one
suppossed to change the value of System.in and System.out when
they are defined and final? This can not be done in java code
(which is why the Sun JDK does it in native code).
(sig of the fields in System)
public final static InputStream in;
public final static PrintStream out;
public final static PrintStream err;

I am no sun lover but I that does not change the fact that japhar
crashes with every jdk classes.zip that I have tried (I have tried
about 10 differnet JDKs from different verdors and they all break!).
