help on classpath on ppc 405

[Fabio Antonini]

Hi all
my name is Fabio Antonini and since the last week I'm evaluating classpath
with jamvm. I'm trying to cross-compile the classpath/jamvm for a ppc405
from a i686 linux based host. When I run the jamvm on a simple hello world
class file I receive the following message 

sh-2.04#  /usr/local/bin/jamvm -verbose -verbosegc -noasyncgc hello

Error initialising VM (initialiseMainThread 

Digging into the code with lots of printf I've seen that the problem arises
inside the initialiseMainThread function when the VM tries to read some
parameters from the class 

thread_class = findSystemClass0("java/lang/Thread"); 

vmThread = findField(thread_class, "vmThread", "Ljava/lang/VMThread;");
daemon = findField(thread_class, "daemon", "Z");
name = findField(thread_class, "name", "Ljava/lang/String;");
group = findField(thread_class, "group", "Ljava/lang/ThreadGroup;");
priority = findField(thread_class, "priority", "I"); 

run = findMethod(thread_class, "run", "()V"); 

vmthread_class = findSystemClass0("java/lang/VMThread");
thread = findField(vmthread_class, "thread", "Ljava/lang/Thread;");
vmData = findField(vmthread_class, "vmData", "I");
printf("Hello from Fabio\n");
/* findField and findMethod do not throw an exception... */
if((vmData == NULL) || (run == NULL) || (daemon == NULL) || (name == NULL)
||
    (group == NULL) || (priority == NULL) || (vmThread == NULL) || (thread
== NULL)) 

Any idea about this? Could this be related to the different endianess
between the target and host processors?
Any help will be appreciated.
Thank you in advance
Fabio
