Description

When UDF exception fails, the error message will just mention the top-level exception and none of the causes. This is fine for usual compilation errors but makes it essentially very difficult to identify the root cause.

So, this ticket's about to improve the error messages at the end of the constructor of JavaBasedUDFunction.
