Bug in JNI RegisterNatives?

Wed May 31 12:35:00 GMT 2006

That's what I tried.
But the way JNINativeMethod is defined in jni.h, I cannot forward 
declare it that way. Here's the relevant part from jni.h:
typedef struct
{
	...
} JNINativeMethod;
Changing this would help, but I'm not sure we can do this, as the 
file is part of classpath. But this should work:
typedef struct JNINativeMethod
{
	...
} JNINativeMethod;
Class.h does not foward declare JNIEnv. _Jv_JNIEnv is used at 4 
places, but not declared. I'm a bit puzzled. It must be declared in 
one of the includes, but where?
