According to the spec. of the methods
javax.imageio.ImageTypeSpecifier.createBufferedImage and
javax.imageio.ImageTypeSpecifier.getSampleModel
all positive values of parameters width and height are valid.

But with big parameter values these methods throw IllegalArgumentException.

See test source and log below.
---------------------------------------- test.java
package test;

import javax.imageio.ImageTypeSpecifier;
import java.awt.image.BufferedImage;

public class test {

    public static void main(String argv[]) {
        ImageTypeSpecifier itspecifier;
        
        itspecifier = ImageTypeSpecifier.createFromBufferedImageType
            (BufferedImage.TYPE_INT_RGB);
        try {
            itspecifier.createBufferedImage(Integer.MAX_VALUE,
Integer.MAX_VALUE);
        } catch( Throwable e ) {
            System.out.println("createBufferedImage: unexpected "+ e);
        }
        try {
            itspecifier.getSampleModel(Integer.MAX_VALUE, Integer.MAX_VALUE);
        } catch( Throwable e ) {
            System.out.println("getSampleModel: unexpected "+ e);
        }

        System.out.println("END");
    }
