FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
See test script below. First getInterface call returns non-null; second returns null. The only difference is the additional static method. Since static methods are not overrideable, their presence should be of no consequence.

--------

import javax.script.*;

class Test {
	public static void main(String[] args) throws Throwable {
		ScriptEngine engine = new ScriptEngineManager().getEngineByName("JavaScript");
		engine.eval("var obj = { run: function() {} };");
		System.out.println(((Invocable)engine).getInterface(engine.get("obj"), A.class));
		System.out.println(((Invocable)engine).getInterface(engine.get("obj"), B.class));
	}
	
	public interface A {
		void run();
	}
	
	public interface B {
		void run();
		static void foo() {}
	}
}

I know I've filed this bug under the wrong subcategory -- that's your own stupid fault because nothing encompassing javax.script is on the list. Deal with it. I know you won't, though -- I am beyond sick and tired of every bug I report being flagrantly ignored, but I'll keep trying anyway. Perhaps somewhere, someday, someone will at least read one of them.


REPRODUCIBILITY :
