Github user rednaxelafx commented on the issue: https://github.com/apache/spark/pull/19890 I'd LGTM on both upgrading to Janino 3.0.8 and also changing the exception type captured from `JaninoRuntimeException` to the new `InternalCompilerException`. It's never a good idea to have conflicting library version on the classpath anyway, hitting an error in terms of `ClassNotFoundException` or `NoClassDefFoundError` on this new exception type is actually a good hint that there is a version conflict -- it'd be nice if we can document this knowledge somewhere easy to find, though.
