Easily possible. The Jexl options and components were added in several steps by multiple contributors. Feel free to open a separate issue to clean this up. Thanks!

> [Jexl 3.0|https://commons.apache.org/proper/commons-jexl/changes-report.html#a3.0] enforced that a JexlExpression does not contains statements. However, NUTCH-2368 intended that a JexlScript is allowed. Need to switch from JexlExpression to JexlScript in Generator.
> But should also verify whether to fix other components where Jexl is used:
> - JexlExchange
> - JexlIndexingFilter
> - CrawlDbReader
