Hi all,

i want to call an jni-function with an parameter of two-dimensional 
array of int.

The complete example from:

http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/jnistring.html#multi


public class ArrayManipulation {

***snip***
public native void manipulateArray(
		int[][] multiplier, Boolean lock);
***snip***

}


The generation of the c-headerfile failed.

 >/usr/local/kaffe/bin/javac ArrayManipulation.java
 >export CLASSPATH=./:/usr/local/kaffe/jre/lib/rt.jar
 >/usr/local/kaffe/bin/javah ArrayManipulation
bogus array type `['


The attached patch fixed this error.


Thank you
Daniel
