Bug 83248 Warnings in javadoc generation
If you check N20050119-0010/compilelogs/platform.doc.isv.javadoc.txt, you will find that there are a lot of warnings during the javadoc generation of platform plugins. I will attach patches to get rid of them.

	/**
	 * Returns the regular image for the given image descriptor. This caches the
	 * result so that future attempts to get the image for an equivalent or
	 * identical image descriptor will only access the cache. When all
	 * references to equivalent image descriptors are dropped, the images
	 * (regular, gray and disabled) will be cleaned up if they have been
	 * created. This clean up makes no guarantees about how long or when it will
	 * take place.
	 * 
	 * @param descriptor
	 *            The image descriptor with which a regular image should be
	 *            created; may be <code>null</code>.
	 * @return The regular image, either newly created or from the cache. This
	 *         value is <code>null</code> if the image descriptor passed in is
	 *         <code>null</code>. Note that a missing image will be returned
	 *         if a problem occurs in the creation of the image.
