[classlib][lang]API+j9 unexpected ClassFormatError for the method ClassLoader.defineClass(name,
array, 4, -2);
--------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-875
                 URL: http://issues.apache.org/jira/browse/HARMONY-875
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov


The Harmony API+j9 throws ClassFormatError for the method ClassLoader.defineClass(name, array,
4, -2); while RI and API+DRLVM throws ArrayIndexOutOfBoundsException and IndexOutOfBoundsException.

================ test.java ======================
public class test {

    public static void main(String[] args) {
        try {
            testCL cl = new testCL();
            String name = "0";
            byte[] array0 = new byte[] { 2, 2, 2, 2, 2, 2, 2};
            cl.defineKlass(name, array0, 4, -2);
            System.out.println("Test failed");
        } catch (IndexOutOfBoundsException e) {
            System.out.println("Test passed: "+e);
        } catch (Throwable e) {
            System.out.println("Test failed: "+e);
        }
    }
}
class testCL extends ClassLoader {
    public Class defineKlass(String s, byte[] ar,  int i1, int i2) throws ClassFormatError
{
        return super.defineClass(s, ar, i1, i2);
    }
}
