Accessing Kotlin class object from Java

As a workaround, you should be able to make the Kotlin field visible using @JvmField:

@JvmField var addressLocationBox: ToOne? = null

The "absense" of getSomeValue() is a bug in the IDE. If you use it, it compiles OK. I created an issue: http://youtrack.jetbrains.com/issue/KT-3337
