version 2.2.3 can't deserialize some class that verision 2.2.2 can

[yuchangyuan]

Some simple class can successful deserialize with jackson-module-scala v2.2.2, throw com.fasterxml.jackson.databind.JsonMappingException with v2.2.3.

Test code:
https://github.com/yuchangyuan/jackson-test1
https://github.com/yuchangyuan/jackson-test1/blob/master/src/main/scala/test.scala

package me.ycy.jackson.test1

import com.fasterxml.jackson.databind.ObjectMapper
import com.fasterxml.jackson.module.scala.DefaultScalaModule

import java.io.File

class MyObj(val a: String, var b: String) {
  override def toString = s"{a: ${a}, b: ${b}}"
}

object Test {
  def main(args: Array[String]) = {
    val mapper = new ObjectMapper()
    mapper.registerModule(DefaultScalaModule)

    val obj = new MyObj("abc", "efg")
    val str = mapper.writeValueAsString(obj)
    println(s"str = ${str}")
    val obj1 = mapper.readValue(str, classOf[MyObj])
    println("obj = " + obj1.toString)
  }
}

and build.sbt

// -*- mode: scala -*
import AssemblyKeys._

organization := "me.ycy"

name := "jackson-test1"

scalaVersion := "2.10.2"

version := "0.1"

  "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.2.3",

)

The output is here:

But if I change jackson-module-scala version to 2.2.2, while keep jackson-databind version unchanged(v2.2.3), everything is ok(that's why I think this is a jackson-module-scala issue, not jackson-databind):

This was caused by my attempts at a fix for #83, which in turn is caused by FasterXML/jackson-databind#318.

For 2.3 (and 2.2.4, if there ever is one), I'll revert the fix for #83, as it's a bit of an esoteric use case, and hopefully be able to get a fix into databind for that use case.

[yuchangyuan]

Just find out that I try v2.2.3 for #73 (and then find this issue), and just confirm that v2.2.3 actually fix my problem(#73) happened with v2.2.2, so I have to wait v2.3(or v2.2.4) for both to be fixed.

Version 2.3.0-rc1 has been released with this fix. It'd be a big help if you could try out the release candidate and let us know if you have any issues.

[yuchangyuan]

Thank you, the problem disappear after switch to 2.3.0-rc1, test with both jackson-test1 test code and my real code.

Great, thanks for your feedback!
