This seems fine to me. Do you have a lot of code where you're returning IRubyObject types from an interface impl into Java? |

Ok cool, thanks for confirming that. Good patch. |

Same as #4777 but for the return type.
There is no point in running the typecast if the return type is an
IRubyObject:)That said ... small disclaimer:
I'm a little unsure I didn't make a mistake here, functionally this seems fine in my testing (and is fairly straightforward imo) but the performance gain is much bigger than that from #4777.
The
org.jruby.benchmark.JavaInterfaceBenchmark#benchHalfRubyVersionbenchmark goes from0.036ops/nsto0.045ops/nsfor me, which seems like an unexpectedly huge increase.
