Can't we use checkFromToIndex​ for this IOOBE too? Used in many other places in this PR...

Please also confirm all tests modified are green after this modification..

checkFromToIndex​ has different semantice with checkIndex:

  • checkFromToIndex
     * <ul>
     *  <li>{@code fromIndex < 0}</li>
     *  <li>{@code fromIndex > toIndex}</li>
     *  <li>{@code toIndex > length}</li>
     *  <li>{@code length < 0}, which is implied from the former inequalities</li>
     * </ul>
  • checkIndex
     * <ul>
     *  <li>{@code index < 0}</li>
     *  <li>{@code index >= length}</li>
     *  <li>{@code length < 0}, which is implied from the former inequalities</li>
     * </ul>

The following tests are passed after applying this patch:

test/jdk/javax/imageio/AppletResourceTest.java
test/jdk/javax/imageio/ImageReaderReadAll.java
test/jdk/javax/imageio/metadata/IIOMetadataFormat/UserPluginMetadataFormatTest.java

ClippedImages.java is a manual test, I have no environment to test it, but since it's a trivial replacement, I think it's okay..

I meant

if (imageIndex < minIndex)
                    throw new IndexOutOfBoundsException();

can't it be replaced with Objects.checkFromToIndex(minIndex, imageIndex, ..

Hi, sorry for the late response. checkFromToIndex has many constraints, this code may not satisfy those constraints, so I don't think we should do that in this PR.(Maybe we can file a new PR to do replacement carefully)

OK...The subject line of this PR states that checkFromToIndex will also be used but I see only checkIndex so I intervened. Anyways, the code in question is in test so not much of an issue.

Thanks @prsadhuk for review! I've updated the title to exclude checkFromToIndex.
