The problem is that for a simple AWT program that just displays a frame, the method GetJavaVM( ) gets called somewhere along the way. This in turn calls the native method CreateJavaVM( ), which raises an unimplementedNativeMethod exception. I have shown a snippet of the error at the bottom of this message.
I looked around in the code for CreateJavaVM and found confusing inconsistencies. Its declared in VM_JNIFunctions.java and implemented in a file (syswrap.C) which isn't even compiled into the VM default. There seems to be a typo in the implementation (non-matching function prototype), and when I forced this file to be recompiled, I wasn't able to run any programs at all. I don't see how someone could possibly get AWT working without addressing this CreateJavaVM problem. I want to know how they got past this error. Here again is a snippet of the error message: Lcom/ibm/JikesRVM/VM_DynamicLinker; unimplementedNativeMethod()V at line 41 Lcom/ibm/JikesRVM/jni/VM_JNIFunctions; GetJavaVM(Lcom/ibm/JikesRVM/jni/VM_JNIEnvironment;Lcom/ibm/JikesRVM/VM_Address;) I at line 5395 <native frame> <native frame> Lgnu/java/awt/peer/gtk/GtkMainThread; gtkInit(I)V at line 0 Lgnu/java/awt/peer/gtk/GtkMainThread; run()V at line 102 Ljava/lang/Thread; run()V at line 270 Lcom/ibm/JikesRVM/VM_Thread; startoff()V at line 779 JikesRVM: exit 124 On Thu, 9 Dec 2004, Michael Koch wrote: > Am Donnerstag, 9.
