JRuby 10.0.1.0 / 10.0.2.0 had a small regression on Java integration due: 6e0f8bd
RubyModule#hashCode() ends up being called while setting up Java proxies, when interfaces are implemented, leading to:
public class SampleClassWithHashMethod implements Cloneable {
public static int hash(Object arg) {
return 42;
}
}ArgumentError:
no method 'hash' (for zero arguments) on Java::SampleClassWithHashMethod

this happens when the target Java class has a (static) hash(...) method, believe this wasn't intended with the change...
