> ZipOutputStream.write(null, offset, length) exception throwing order differs on Harmony
and RI 
> This method throws NullPointerException on Harmony if byte array is null and length (or
offset) is negative, but throw IndexOutOfBoundsException on RI. 
> For me throwing NullPointerException is more appropriate here (taking into account that
both IndexOutOfBoundsException and 
> NullPointerException possible according to Java API Spec), so bug was created only to
record non-bug difference between Harmony and RI.
> Please, feel free to close the issue if you agree with this.
> Consider the following code:
> import java.io.File;
> import java.io.FileOutputStream;
> import java.io.IOException;
> import java.util.zip.ZipOutputStream;
> public class writeTest {
> 	static byte[] data = null;
> 	
> 	public static void main(String[] args) throws IOException {
> 		File test = new File("test.zip");
> 		test.createNewFile();
> 		FileOutputStream out = new FileOutputStream(test.getName());
> 		ZipOutputStream zipout = new ZipOutputStream(out);
> 		try {
> 			zipout.write(data, 0, -2);
> 		} catch (Exception e) {
> 			System.out.println(e);
> 		}
> 	}
> }
