Re: Java interop: Can't call public method of non-public class
Hey Sean,
Your attempt worked because in Netty 4.0.0.Alpha8
AbstractBootstraphttps://github.com/netty/netty/commit/23438de66f82c72720b092c539bb430995722d2d#transport/src/main/java/io/netty/bootstrap/AbstractBootstrap.java
was
still public.. Try it out with 4.0.0.Beta2..
Thanks!

Re: Java interop: Can't call public method of non-public class
When you annotate, is it a runtime or a compile-time error? I would be very surprised if it happened at runtime (when the function is actuall called).

It is almost certain that the method you want to call is inherited from a public ancestor. Annotate the call with that ancestor and it will work.

Re: Java interop: Can't call public method of non-public class
It does have a public descendant, though. It is not acceptable for you to
annotate with ServerBootstrap? It really is bad practice to annotate with
non-public classes.

Re: Java interop: Can't call public method of non-public class
Detailed finding: it *doesn't* fail at compile time; it always fails at
runtime.
Reason: at compile time there is a *reflection warning*, which means that
the method wasn't found and a reflective call was emited by the compiler.

Re: Java interop: Can't call public method of non-public class
You didn't recompile everything, that's the reason. I got the same error the first time, that's how I realized that the child had overridden the method. This is an interesting finding in itself: javac provides the override precisely to avoid pitfalls such as this one. If the parent was public, this wouldn't have happened. Anyway, to make it really minimal, put all the java code into a single ConcreteChild.java.

Re: Java interop: Can't call public method of non-public class
Yes, the error is there. I also created a *lein new app* project, which by
default creates a gen-classed main namespace:
(ns call-test.core (:gen-class))
(set! *warn-on-reflection* true)
(defn -main [ args] (.x (test.ConcreteChild.)))
Now try *lein do clean, uberjar. *It will report a reflection warning while
AOT-compiling.
Then do *java -jar target/call-test-0.1.0-SNAPSHOT-standalone.jar *and see
it fail.
This cleanly separates compile time from runtime.

Re: Java interop: Can't call public method of non-public class
Hm. You shouldn't have made ConcreteChild a nested class, that is a
distraction that may set people on a wrong trail. In Java you are allowed
to have as many package-private classes as you wish; the constraint is only
on one *public* class. If you had ConcreteChild.java with this in it:
abstract class AbstractParent {
public final int x() { return 6; }
}
public class ConcreteChild extends AbstractParent {}
it would have compiled.

Re: Java interop: Can't call public method of non-public class
I found the following work-around since I have access to the java code I am
calling:
I had the package-visible ABC Bytes implement a (public) interface
declaring the toHexString method. This placated the compiler.

If you are interseted in a workaround, type-hinting the code will work (my
guess).

new Hash().toHexString();

Re: Can't call public method of non-public class
That's the one. But the solution given by the bug reporter doesn't address the case that came up on this thread, since it's not the class of the invocant but the types of the parameters that prevent the match from being found.

Re: Can't call public method of non-public class
This looks like the old type erasure problem - the returned map is of a private class, so clojure looks for a public version of the put method in one of the interfaces/base classes - but does an exact comparison on parameter types, so put(String, String) doesn't match put(Object, Object) and the search fails. You might think that the Reflection API would provide a way of looking for methods that you could call with the types given, instead of just exact match, but using getMethod() or getDeclaredMethod() instead of looping and comparing manually yields the same result. However, as mentioned at http://christerblog.wordpress.com/2010/02/27/java-reflection-matching-formal-parameter-list-to-actual-parameter-list/ , the Coherence Common Incubator project has a ReflectorHelper module that provides a solution (at least in the case of constructors); I''m thinking Clojure could adapt/adopt that solution.

Re: Can't call public method of non-public class
You probably can't. I think hints only go in binding declarations. I'd use 'env', as you're probably doing already. But let's keep an eye on Mark's patch, as it'd be much better to avoid an explicit upcasting. On Mar 23, 7:38 pm, Konstantin Barskiy zuftw...@gmail.com wrote: Thanks a lot!
