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..
