"L" is the type signature for a class. "J" should be the right string here according to https://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/types.html#wp276

I think we should use "Long" in function Names instead of "Int64" since the original JNI API also uses "Long" (GetLongField()etc.) and I think we should stick to it.
Though I see that from a Swift standpoint this might be weird.
Not sure what @ephemer thinks about that.

I agree with @rikner in that we should call it We're getting what we defined in Java as a |

we should define this as an extension on JavaLong, and return / cast values to JavaLong wherever relevant - it's the same type, but it makes the API's intent clearer

we don't need to recast a JavaLong to a JavaLong :)

This adds the ability to pass
Int64/JavaLongsbetween worlds.I'm not quite sure if the naming of the functions is correct. Do we want to
getInt64Fieldsor do we want togetLongFields?
