But that gives:

/Users/shamsasari/git/corda/finance/src/main/java/net/corda/contracts/JavaCommercialPaper.java:59: error: foo() in Test cannot override foo() in TestB
        public Unit foo() {
                    ^
  return type Unit is not compatible with void

@okkero Should I create a bug ticket or wait for a member of JB to respond?

if there is no such report on YouTrack already, I'd just go for it...

Is possible enable

kotlin-allopen

plugin only for test task in gradle?

you have to put annotations into production classes so I think answer is clear...

It’s not necessary. Plugin afects only runtime behavior. You still won’t be able to extend such classes in code so it doesn’t make sense to enable it only for tests.

As far as I understand it. Didn’t use though.

there is an open issue about it

@oshai, are you tell about this issue? https://youtrack.jetbrains.com/issue/KT-15767

yes

Hello all, does anybody know how to mock an extension function with mockito?

I don’t think you can. Extension methods are actually just static methods

We use powermock for any static methods

That's interesting, when I try to mock the extension method it just seems to ignore my mock and go directly to the real implementation of the method. Ill take a look at powermock

This isn’t necessarily Kotlin specific, but is anyone aware of a simple library to handle persistence which allows you to add listeners for object modification, creation, and deletion? So far I’ve found Hazelcast, and have also considered rolling my own using the plain-old-filesystem for storage (perhaps using Gson for serialization).

well, lots of persistence frameworks do that

hibernate, ORMS do that. requery for instance is one we're looking at, at the moment

there's jsimpledb

it depends what you mean by "simple" i guess.

Is Kotlin 1.1 bytecode binary compatible with Kotlin 1.0?

Yes.

@gkt But stdlib has some differences, so beware!

Anyone seeing messages like this from the kotlin bytecode viewer in IJ:

java.lang.IllegalStateException: More than one package fragment, files: [JetFile: FooTest.kt, JetFile: FooInlined.kt] | fragments: [package foo.bar, package foo.bar]

(It's in a class that imports some inline functions)

When doing class delegation, Kotlin appears to prefer calling methods in the supertype rather than the derived type for overloaded functions... is there a way to prevent this?

Can you post a code snippet?

Could not update kotlin plugin to 1.1.0-beta-22-IJ2016.3-1. Multiple warnings in IDEA logs:

WARN - finder.JvmIDEVirtualFileFinder - There are 3 classes with same fqName: kotlin/ArrayIntrinsicsKt found

@mikehearn re: persistence frameworks, I’m hoping for something a lot simpler than an ORM or even a SQL database, perhaps a key-value store

@mikehearn Ideally something that doesn’t rely on an external process, something that just runs in the JVM
