    Can you try
    ```
    import org.apache.spark.sql._
    import org.apache.spark.sql.functions._
    import org.apache.spark.sql.expressions._
    import org.apache.spark.sql.types._
    
    udf((v: String) => v.stripSuffix("-abc"))
    ```
    and see if it throws something like the following exception?
    ```
    error: object lang is not a member of package org.apache.spark.sql.expressions.java
          val normalizeVersion = udf((v: java.lang.String) => v.stripSuffix("-abc"))
    ```
