java.lang.reflect.Proxy support with native code?

I've attached a simple example, and below is the outcome of executing:

---------------------
In cygwin with "GCJ (GCC) 3.3.1 (cygming special)" I get:

$ ./ProxyTest2.exe
1: starting...
2: classloader: gnu.gcj.runtime.VMClassLoader@1012f810
Exception in thread "main"       5 [main] ProxyTest2 2252 
fhandler_base::fork_fixup:  - Win32 error 6, handle io_handle<0x4B8>
=== SNIP ===
java.lang.InternalError: Unexpected: java.lang.NoClassDefFoundError: 
while resolving class: $Proxy0
    <<No stacktrace available>>
Caused by: java.lang.NoClassDefFoundError: while resolving class: $Proxy0
    <<No stacktrace available>>
Caused by: java.lang.ClassNotFoundException: 
java.lang.reflect.UndeclaredThrowableException not found in [file:./, 
core:/]
    <<No stacktrace available>>


---------------------
With MinGW and "gcj.exe (GCC) 3.4.0 (mingw special)" I get:

$ ./ProxyTest2.exe
1: starting...
2: classloader: gnu.gcj.runtime.VMClassLoader@bbdfc0
Exception in thread "main" java.lang.InternalError: Unexpected: 
java.lang.NoClassDefFoundError: while resolving class: $Proxy0
=== SNIP ===


---------------------
With my gcj-crosscompiler "powerpc-405-linux-gnu-gcj (GCC) 3.4.0" I get 
all the way past 4), but then it dies:

# ./ProxyTest2
1: starting...
2: classloader: gnu.gcj.runtime.VMClassLoader@10073fc0
3: proxyClass: class $Proxy0
4: constructor: public $Proxy0(java.lang.reflect.InvocationHandler)
Illegal instruction


I wonder if the two initial tests die because these are static build, 
whereas the final one isn't.
