Description

RI throws unspecified ArrayIndexOutOfBoundsException for java.awt.image.DataBufferByte(int size, int numBanks) when numBanks == 0, while Harmony works silently.
Test to reproduce:
----------- test.java -------------
import junit.framework.TestCase;
import junit.textui.TestRunner;

import java.awt.image.DataBufferByte;

public class test extends TestCase {
public static void main(String args[])

{ TestRunner.run(test.class); }

public void testRun() {
try

{ DataBufferByte db = new DataBufferByte(21, 0); fail("ArrayIndexOutOfBoundsException expected"); }

catch (ArrayIndexOutOfBoundsException expectedException)

{ // Expected expectedException.printStackTrace(); }

}
}
-------------------------------
Output RI:

OK (1 test)

Output Harmony:

There was 1 failure:

FAILURES!!!
Tests run: 1, Failures: 1, Errors: 0

I suggest to resolve this bug as non-bug difference since there is nothing said in spec about any exceptions in DataBuffer constructor and it is not obvious what was the reason of failure on RI.
