Hyukjin Kwon resolved SPARK-23453.
----------------------------------
Resolution: Incomplete
> ToolBox compiled Spark UDAF causes java.lang.InternalError: Malformed class name
> --------------------------------------------------------------------------------

> Key: SPARK-23453
> URL: https://issues.apache.org/jira/browse/SPARK-23453
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.1
> Environment: Spark 2.2.1
> Scala 2.11.11
> JDK 1.8
> Reporter: Eric Lo
> Priority: Major

> Here is a weird problem I just ran into... My scenario is that I need to compile UDAF dynamically at runtime but it never worked.
> I am using Scala 2.11.11 and Spark 2.2.1, please refer to my [StackOverflow post|https://stackoverflow.com/questions/48820212/toolbox-compiled-spark-udaf-causes-java-lang-internalerror-malformed-class-name] for detailed information and minimal examples. The problem itself is very similar to other Malformed class name tickets (for example -[https://github.com/apache/spark/pull/9568])- which were caused by calling getSimpleName of nested class/object but actually it is different in this case and the problem is still there. The getSimpleName issue has been fixed in Java 9 which Spark doesn't support it yet...so...any solution/workaround is appreciated.
