spec: getObjectClass description is self contradictory

Name: dkR10031 Date: 04/12/2001


Specification of the method
javax.imageio.metadata.IIOMetadataFormatImpl.getObjectClass says:

"Returns the Class type of the Object reference stored within the element.
If null, this element may not contain an Object reference. ...
Returns:
         a Class object, or null."

The same description states:

"Throws: ...
    IllegalArgumentException - if the named element cannot contain an object
    value (i.e., if getObjectValueType(elementName) == VALUE_NONE).

These two statements contradict each other.
Note that implementation (JDK 1.4.0beta, build b59) of the method does
throw the exception.

This bug affects new JCK test:
api/javax_imageio/metadata/IIOMetadataFormatImpl/index.html#getObjectClass
