According to the spec. ImageTypeSpecifier constructors should throw
IllegalArgumentException if either parameter is null.
But they do not throw IllegalArgumentException as expected.

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

import javax.imageio.ImageTypeSpecifier;

public class test {

    public static void main(String argv[]) {

        try {
            ImageTypeSpecifier itspecifier = new ImageTypeSpecifier( null,
null);
            System.out.println("Ctor1 failed");
        } catch( IllegalArgumentException e ) {
            System.out.println("Ctor1 passed");
        } catch( Throwable ee ) {
            System.out.println("Ctor1: unexpected "+ ee);
        }
        try {
            ImageTypeSpecifier itspecifier = new ImageTypeSpecifier(null);
            System.out.println("Ctor2 failed");
        } catch( IllegalArgumentException e ) {
            System.out.println("Ctor2 passed");
        } catch( Throwable ee ) {
            System.out.println("Ctor2: unexpected "+ ee);
        }
    }
}
