When one adds @ignore tag to a test description like:

/*
 * @test
 * @ignore bug
 * @library lib
 * @run main/othervm Test2
 */
public class Test2 {
    public static void main(String args[]) {
        System.out.println("Hello world");
    }
}

and then run this test as:

jtreg -ignore:run Test2.java

He or she will get an error:
test result: Error. Parse Exception: `@library' must appear before first `@run'

Which is very confusing... Because library goes before run.

It would be better to report that
`@library' must appear before first action tag (`@run', '@igonre',...)
