Eelco Hillenius resolved AVRO-94.
---------------------------------
Resolution: Invalid
I just came across this comment:
/** Generate a protocol for a Java interface.
* <p>Note that this requires that <a
* href="http://paranamer.codehaus.org/";>Paranamer</a> is run over compiled
* interface declarations, since Java 6 reflection does not provide access to
* method parameter names. See Avro's build.xml for an example. </p>
*/
Big duh again... that pretty much explains this whole issue. I was testing from
Eclipse directly, so paranamer was never included into the compilation.
Resolving this issue as invalid.

> Not sure whether this is a bug in Paranamer or whether Avro has the wrong
> expectations, but currently TestReflect#testProtocol throws an
> ArrayIndexOutOfBoundsException due to this problem, and
> http://mail-archives.apache.org/mod_mbox/hadoop-avro-user/200908.mbox/%[email protected]%3e
> seems to point to that same problem.
> In ReflectData#getMessage:
> {code}
> String[] paramNames = PARANAMER.lookupParameterNames(method);
> java.lang.reflect.Type[] paramTypes = method.getGenericParameterTypes();
> for (int i = 0; i < paramTypes.length; i++)
> fields.put(paramNames[i], <-- in the test, paramNames has lenght 0, while
> paramTypes has length 1
> {code}
