ArrayIndexOutOfBoundsException raises when Combining specific args with required.

i use

• jruby-complete-1.7.12
• JDK1.7.0_21 or JDK1.8.0

code is

import org.jruby.Ruby;
import org.jruby.RubyClass;
import org.jruby.RubyObject;
import org.jruby.anno.JRubyMethod;
import org.jruby.javasupport.JavaEmbedUtils;
import org.jruby.runtime.ObjectAllocator;
import org.jruby.runtime.builtin.IRubyObject;

public class Bug extends RubyObject {

    public Bug(Ruby r, RubyClass rc) {
        super(r, rc);
    }

    @JRubyMethod(required=1)
    public void test(IRubyObject a, IRubyObject[] args) {}

    public static void main(String[] args) {
        Ruby r =JavaEmbedUtils.initialize(new java.util.ArrayList<>());
        r.defineClass("Bug", r.getObject(), new ObjectAllocator() {
            @Override
            public IRubyObject allocate(Ruby runtime, RubyClass klazz) {
                return new Bug(runtime, klazz);
            }
        }).defineAnnotatedMethods(Bug.class);
    }
}

this code happen to ArrayIndexOutOfBoundsException

this is actually how the extension API works (even in 9K) - you get all of the arguments in a single [array] when it's part of the method signature ... but you can use over-loads to handle cases based on argument count ... if that helps
