Actually, Java.wrap wants the recv parameter to be JavaUtilities, so you'd
need to do something like this:
return Java.wrap(recv.getRuntime().getModule("JavaUtilities"),
JavaObject.wrap(recv.getRuntime(),c.prepareStatement(sql.toString())));
You could also call Java.java_to_ruby, but it adds a lot of overhead that is
unnecessary in this case -- it will unwrap the JavaObject, do a lot of type
checking (in JavaUtil.convertJavaToRuby), and in this case just rewrap it in
a JavaObject. (We should probably have Java-facing versions of some of
these methods that avoid unnecessary wrapping-unwrapping.)
return Java.java_to_ruby(recv,
JavaObject.wrap(recv.getRuntime(),c.prepareStatement(sql.toString())),
Block.NULL_BLOCK);

I haven't tried this (yet, will shortly), but I think what you need to do
is:
return Java.wrap(recv,JavaObject.wrap(
recv.getRuntime(),c.prepareStatement(sql.toString())))
Otherwise you're just returning a raw JavaObject, with no proxy (hence no
methods).
