I've had the same problem with jrubyc compiled classes that you
mentioned in point (3). Decompiling shows methods like this in the
Java class:
public class MyClass extends AbstractScript {...
public IRubyObject initialize__5(ThreadContext threadcontext,
IRubyObject irubyobject,
IRubyObject[] irubyobjects, Block
block) {... }
public IRubyObject method1__6(ThreadContext threadcontext,
IRubyObject irubyobject,
IRubyObject[] irubyobjects, Block block) {... }
I was expecting:
public class MyClass extends RubyObject {
public MyClass(Object arg1, Object arg2) {... }
public Object method1(Object arg1) {... }
