Re: Bug in JNI RegisterNatives?

[Juerg Lehni <juerg at scratchdisk dot com>]

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?
