Runtime exception when unpickling Array of tuple #75

Closed lilZ420 closed 10 years ago

lilZ420 commented 10 years ago

Below is a use case to produce a runtime exception when unpickling an Array of tuple.

import scala.pickling. import json. object JsonTest extends App { val simplePickled = new Simple(Array(("test", 3))).pickle.unpickle[Simple] } class Simple(val x: Array[(String, Int)]) {}

What error are you getting? I'm getting a "Scala field hd isn't represented as a Java field, neither it has a Java accessor method" and I'm wondering if the issue is associated.
