JFLI with LWM

Dear List

I am trying run JFLI (Java Foreign Language Interface for CL) with LispWorks 6.0.1 on MacOSX 10.6.7

Following the quickstart tutorial, I can set the JVM path and start it (apparently successfully) :

(setf *jni-lib-path* "/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/JavaVM.framework/JavaVM")

(create-jvm (concatenate 'string "-Djava.class.path=" (namestring (current-pathname "jfli/jfli.jar"))))
=> 0, #<Pointer: JNI:PVM = #x0861BAF8>, #<Pointer: JNI:PENV = #x09800118>

However, I get a bus error as soon as I try to define the first binding :

(def-java-class "java.lang.Object")

Bus error(10) [code 0] at 0
eax        0 ; ebx B0734DF0 ; ecx 219FBD8E ; edx  103A800
esp B0734DDC ; ebp EE8FE834 ; esi 20071A42 ; edi  101CC00

Does someone have some experience with JFLI on MacOSX ?
Thanks for any help or advise!
