[jira] [Updated] (SPARK-29497) Cannot assign instance of java.lang.invoke.SerializedLambda to field

Description: 
Note this is for scala 2.12:

There seems to be an issue in spark with serializing a udf that is created from 
a function assigned to a class member that references another function assigned 
to a class member. This is similar to 
https://issues.apache.org/jira/browse/SPARK-25047 but it looks like the 
resolution has an issue with this case. After trimming it down to the base 
issue I came up with the following to reproduce:

 

 
{code:java}
object TestLambdaShell extends Serializable {
  val hello: String => String = s => s"hello $s!"  
  val lambdaTest: String => String = hello( _ )  
  def functionTest: String => String = hello( _ )
}

val hello = udf( TestLambdaShell.hello )
val functionTest = udf( TestLambdaShell.functionTest )
val lambdaTest = udf( TestLambdaShell.lambdaTest )

sc.parallelize(Seq("world"),1).toDF("test").select(hello($"test")).show(1)
sc.parallelize(Seq("world"),1).toDF("test").select(functionTest($"test")).show(1)
sc.parallelize(Seq("world"),1).toDF("test").select(lambdaTest($"test")).show(1)
{code}
 

All of which works except the last line which results in an exception on the 
executors:

 
{code:java}

java.lang.invoke.SerializedLambda to field
