  /* We must create the following classes and array first. This will
     allow us to create java/lang/Class instances.

     Initialization is done in a special way. Initialization checks
     that there is no <clinit> method.  This is a requirement SableVM
     imposes on classes internally created.

     Rationale: Initialization can possibly cause the execution of an
     arbitrary amount of bytecode in an unrestricted number of
     classes.  At bootstrapping time, though, SableVM is not yet ready
     to run arbitrary code.

     If you really need to use static initializers in such classes,
     simply put your static initializers in static inner classes;
     you'll achieve equivalent semantics while also complying with
     SableVM's "no <clinit>" requirement. *[::]/

     "java/lang/Class" was't yet created, so _svmf_create_class and

     The constructor of java.lang.Class should look like this:

     private Class(byte[] vmData)

     this.vmData = vmData;

     In bytecode:

     0 aload_0
     1 invokespecial <Method java.lang.Object()>
     4 aload_0
     5 aload_1
     6 putfield <Field byte[] vmData>
     9 return


     *** Update for Classpath 0.06 ************************************

     With Classpath 0.06 the constructor of java.lang.Class looks like:

     Class(RawData vmData)
     {
     this.vmClass = new VMClass(vmData);
     this.vmData = vmData;
     }

     Ideally, it should look like:

     Class(VMClass vmClass)
     {
     this.vmClass = vmClass;
     }

     We are still in transition towards the VM{Classes} interface.

     Note also that RawData still correspond to a Java byte[].  In
     other words the runtime type of RawData is byte[] although its
     compile type is RawData.  It is still used the same way as before.
