I am getting an error when using the Table API with ScalarFunction. This is
previously reported here (https://issues.apache.org/jira/browse/FLINK-7490)
as loading a wrong class loader and is reported as fixed. But the issue
persists even after using the latest code from 1.3 branch.

https://github.com/apache/flink/blob/master/flink-libraries/flink-table/src/main/scala/org/apache/flink/table/functions/utils/UserDefinedFunctionUtils.scala#L746
Our application is such that the ScalarFunction is defined and instantiated
in a different package from where the topology is executed. Any direction on
how to work around this or what I am doing wrong is much appreciated!
Thanks,
