------------------------------------

             Summary: scala package class case class on flink sql
                 Key: FLINK-19825
                 URL: https://issues.apache.org/jira/browse/FLINK-19825
             Project: Flink
          Issue Type: Bug
          Components: API / Scala
    Affects Versions: 1.11.1
         Environment: flink version: 1.11.1

scala version: 2.12
            Reporter: Yanzhao Deng
         Attachments: NewApiTest.scala, error.txt, package.scala

When I use Flink SQL scala API, I found a bug. I have a sensor.txt, the txt file has some sensor data.One row of data is as follows:
{code:java}
sensor_1,1547718199,35.8
{code}
And I have a `package object MyTest` class. This class has a case class `SensorReading`.
{code:java}
package object MyTest {
    case class SensorReading(id: String, timestamp: Long, temperature: Double)
}
{code}
When I use Flink SQL API, I think he should output the correct result, but he reported an error.
{code:java}
tEnv.createTemporaryView("ds", dataStream)
val result: Table = tEnv.sqlQuery("SELECT * FROM ds where `temperature` >= 5")
result.toAppendStream[SensorReading].print("test"){code}
I will send you the error as a file later. And I found Inner class and scala General class not send this error.
If you have any findings, please contact me.
