[classlib][imageio] ImageIO.read works incorrect

                 Key: HARMONY-4222
                 URL: https://issues.apache.org/jira/browse/HARMONY-4222
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Dmitry Irlyanov
         Attachments: H4222-ImageIOTest.patch

If the ImageIOTest complete with 2 additional specified image formats to read the test fails
both on ibm j9 and drlvm:

package javax.imageio;

import java.net.URL;
import java.util.LinkedList;
import java.util.List;

import junit.framework.TestCase;

public class ImageIOTest extends TestCase {

    public void testReadURL() throws Exception {
        // Regression for HARMONY-3135
        for (URL url : listImages()) {
            assertNotNull("Failed to load image from URL " + url,
            assertFalse("The current thread has been interrupted! URL: " + url, //$NON-NLS-1$

    protected List<URL> listImages() {
        final String imgPath = "/resources/images/utest."; //$NON-NLS-1$
        final Class<? extends ImageIOTest> c = getClass();
        final List<URL> img = new LinkedList<URL>();

        img.add(c.getResource(imgPath + "jpg")); //$NON-NLS-1$
        img.add(c.getResource(imgPath + "png")); //$NON-NLS-1$
	img.add(c.getResource(imgPath + "gif")); //$NON-NLS-1$
	img.add(c.getResource(imgPath + "bmp")); //$NON-NLS-1$
        return img;

on Harmony readImage method cannot read gif and bmp formats:

Failed to load image from URL file:/C:/workspace/Harmony/trunk/working_classlib/modules/imageio/bin/test/resources/images/utest.gif

junit.framework.AssertionFailedError: Failed to load image from URL file:/modules/imageio/bin/test/resources/images/utest.gif
at javax.imageio.ImageIOTest.testReadURL(ImageIOTest.java:31) at java.lang.reflect.VMReflection.invokeMethod(VMReflection.java)

on ibm j9 the readImage throws Decompression Error:
