FULL PRODUCT VERSION :
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b05)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows 7 x64 [Version 6.1.7601]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Am using MinGW 20120426 (gcc port) as C compiler.

A DESCRIPTION OF THE PROBLEM :
Am building a custom JNI library.

gcc is configured to search JAVA_HOME\include so that jni.h can be found.

jni.h includes "jni_md.h" (line 27). This fails as the compiler cannot find "jni_md.h". The file exists in the directory "win32", one level down.

Line 27 should probably read:
#include "win32/jni_md.h"


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a .c file containing the line:
#include "jni.h"

Attempt to compile it.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Manually copy jni_md.h from include/win32 to include.
